High-Performance MEMS Microphone with 69dB(A) SNR and Lowest Distortion

The IM69D130 is designed for applications where low self-noise (high SNR), wide dynamic range, low distortion and a high acoustic overload point is required.

IM69D130 is a high-performance digital MEMS microphone making use of Infineon’s Dual Backplate MEMS technology to deliver 105dB dynamic range and high output linearity up to 130dBSPL. The application benefits are crystal-clear audio signals, extended pick-up distance and sensitivity to both soft and loud signals – from whispered speech to rock concerts.

Infineon’s Dual Backplate MEMS technology is based on a miniaturized symmetrical microphone design, similar to studio condenser microphones, and results in high linearity of the output signal within a dynamic range of 105dB. The microphone distortion does not exceed 1% even at sound pressure levels of 128dBSPL. The flat frequency response (28Hz low frequency roll-off) and tight manufacturing tolerance result in close phase matching of the microphones, which is important for multi-microphone (array) applications.

The digital microphone ASIC contains an extremely low noise preamplifier and a high-performance sigma-delta ADC. Different power modes can be selected in order to suit specific current consumption requirements.

Each IM69D130 microphone is trimmed with an advanced IFX calibration algorithm, resulting in small sensitivity tolerances (±1dB). The phase response is tightly matched (±2°) between microphones, in order to support beamforming applications.

Minimal Audio Signal Latency Enabled by an Ultra-Low Microphone Group Delay

The IM69D130 is designed to be an extremely low latency digital microphone – aimed at applications such as active noise cancellation, where audio data must be processed extremely quickly.

By delivering best-in-class group delay performance, the IM69D130 brings the system design benefits of digital microphones to many areas which had to use analog up to now.

FEATURES

• 69dB(A) signal-to-noise ratio• Below 1% distortion at 128dBSPL (130dBSPL AOP)• Digital (PDM) interface with 6μs group delay at 1kHz• Tight sensitivity (-36 ±1dB) and phase (±2°) tolerances• 28Hz low frequency roll-off• 980μA current consumption (300μA in low-power mode)

BENEFITS

• Far field and soft audio signal pick-up• Clear audio signals even at high sound pressure levels• Enabling precise steering of audio beams for advanced audio algorithms

APPLICATIONS

• Voice User Interface (VUI): e.g. smart speaker, home automation and IoT devices

• Active Noise Cancellation (ANC): headphones and earphones• High-quality audio capturing: e.g. cameras, camcorders, conference

systems• Audio pattern detection: industrial or home monitoring

New Precision Audio Resistor, the RS Series

Susumu, an innovative precision thin film chip resistor manufacturer, introduces the RS series, a new chip resistor series specially created for audio applications.

Thin film resistors have been known to have better frequency characteristics, less noise, and less signal distortion than other types of resistors. It seems clear that for audio applications, the natural choice should be a thin film resistor. However until now, the usage of thin film resistors has been limited to high end audio despite the fact that the most popular audio devices on the market today are smartphones and automotive audio systems. Susumu contends that the sound quality of these popular audio systems can be improved significantly by utilizing thin film resistors, such as Susumu’s RG series. However, Susumu wanted to make the

RG series even better for all audio systems. After numerous prototypes, simulations, and evaluations by sound professionals, Susumu discovered that design methods of resistive patterns and terminal materials had the most impact on sound quality. The RS series was born as a series of thin film resistors targeted specifically for high quality Hi Fi audio applications.

The RS series is a perfect solution for any sound circuits including digital analog converter circuits. If you are interested in improving the sound quality of your audio devices, from high end to personal mobile devices, Susumu’s RS series is the answer to your needs.

Changing the Listening Experience: Ultra-Low-Power Meets a One-Stop Chip

In the last couple of years there has been a re-evolution of the audible space. Small wearable speakers now sit on the wrist and listening home assistant devices sit on the coffee table. What is changing? Consumers are finding immense value with computers that are able to fit in the ear and play music well. Standard audio playback, touch/tap interface, voice trigger, wireless connectivity, motion detection, call handing, and health monitoring are now becoming integrated into the same consumer device.

The modern design discussion is not whether the device is wired or wireless but rather what audible resolution can you push out of a low powered device? What physical or audible control systems are being utilized? What additional sensors can be integrated? And how can features like noise cancellation and sound synchronization enhance the listening experience?

ON Semiconductor’s LC823450 is an ultra-low-power single-chip solution for the re-evolution in the audible space. Compared to the next large-scale integration (LSI) solution the LC823450 has a 1.7 times longer battery life. This device can provide over 120 hours in playback off of two AAA batteries. This is packaged into a small 5.33 x 5.52mm device that integrates an ARM® Cortex®-M3 dual core MCU, proprietary 32-bit DSP, ADC/DAC, high resolution playback, and memory.

Make sure to integrate the RSL10 with the LC823450 for ultra-low-power Bluetooth 5 connectivity.

Mid-Power LEDs: Now a Valid Low-Cost Light Source for Street Lights?

By: Emmanuel Gardette, Field Application Engineer, Future Electronics

LED street lighting designs are entering a new phase. Lighting equipment manufacturers are attempting to maintain all the benefits of LED street lamps – their long operating lifetime, low power consumption, and pleasing light output with good colour rendering – while at the same time substantially reducing the Bill-of-Materials (BoM) cost of the luminaire.

One way to reach this goal appears to be the use of alternative types of LED, replacing today’s high-power LED light sources with cheaper mid-power LEDs. This article describes the technical problems that OEMs face in implementing this change, and the efforts that LED manufacturers are making to support the change.

High-Reliability, High-Power LEDsHigh-power LEDs are a proven light source in street lights installed in some of the hottest as well as some of the coldest parts of the world. Highly dependable, their construction is robust, featuring materials which are immune to corrosion and which tolerate extreme ambient conditions. Normally supplied with ESD protection integrated in the package, high-power LEDs are today in operation in thousands of installations, casting bright white light in precisely shaped beam patterns.

The robustness of high-power LEDs is a crucial part of their appeal to street light OEMs, since the luminaire might be exposed both to extreme temperatures and to air polluted by vehicle exhaust fumes, industrial emissions and other airborne contaminants (see Figure 1).

So while the high unit cost of high-power LEDs – typical price: performance ratios are in the 500lm/$ range – is a deterrent to their use, street light OEMs have until now continued to depend on the devices because of their long-term reliability in harsh outdoor conditions. This continued reliance on high-power LEDs, however, could now be about to end.

Figure 1: Smog over Almaty city, Kazakhstan. LED street lights commonly have to operate in polluted urban air. (Image credit: Igors Jefimovs under CC 3.0 licence)

Mid-Power LEDs: Cheaper, Less RobustThe problem for street light OEMs used to be that the cheaper alternative to high-power LEDs – mid-power LEDs are typically valued at around 1,000lm/$ – also posed too high a risk of premature failure.

That is because mid-power LEDs have a less robust construction than high-power LEDs: a plastic case rather than a ceramic substrate, and a silver-plated leadframe. These components are inherently less resistant to chemical contamination and thermal stress than non-corrodible material, and contamination is indeed one of the new risks associated with the introduction of mid-power LEDs in street lights. Under the benign and stable conditions in which indoor lights operate, this risk does not arise, and so mid-power LEDs are very widely used in indoor luminaires. The broad adoption of mid-power LEDs has led to the development of a rich ecosystem of compatible components, such as optics, drivers and connectors, supporting the leading manufacturers’ families of mid-power LEDs. This ecosystem, as well as their low unit cost, help to make the mid-power LED an attractive choice for manufacturers of street lights.

Outdoors, however, conventional mid-power LEDs are prone to suffer impairment or failure in ways that manufacturers of indoor lighting are not familiar with: • Contamination (sulphuration) of the silver

plated leadframe, which can cause a reduction in flux and colour shift due to oxidation of the metal. In separate detailed application notes, Nichia and LG explain the process and conse-quences of silver sulphuration (see Figure 2).

• Degradation of the plastic case material due to thermal or mechanical stress

• The wire bonding used in mid-power LEDs can break. This effect depends on the ingredient and concentration of the corrosive gas.

At a system level, of course, street light OEMs design their products for a certain Ingress Protection (IP) rating, typically as high as IP68. It might be thought that this gives sufficient protection from contamination. But this is to gamble on the lifetime of the luminaire: • Contamination might reach

the LED in the luminaire’s assembly or maintenance process

• Discoloration by the gases (sulfure, chlorine or other halogen compounds)

• The root cause: silver may turn black (or tarnish) when exposed to gases

• Reaction mechanism: 2Ag + S → Ag2S (black)

Figure 2: The effect of sulphur contamination of a silver leadframe. (Image credit: LG Innotek)

• Materials used to make the luminaire might contain corrosive gases. These might be found in the gasket, glue or paint, for instance.

• Components installed in the luminaire can emit gases in operation

The risk of impairment or failure is clearly worrying for manufacturers of street lights: municipal authorities and other buyers will normally specify extremely long operating lifetimes of 15 years or more, and set tight conditions governing long-term lumen maintenance and, in some cases, colour shift. This means that shifts in correlated color temperature (CCT) – a measure of the relative yellowness or blueness of a fixture’s white light output – flux reductions or catastrophic failures attributable to contami-nation could trigger claims against the fixture manufacturer’s warranty.

How Manufacturers are Hardening Mid-Power LEDs

There is, then, a clear market need for an alter-native to the high-power LED in street lights, one which can both withstand harsh conditions and which is cheaper.

Now LED manufacturers are responding to this need by introducing new families of mid-power LEDs which are hardened for use in street lights. These new devices tend to be produced as two-die packages with a 3030 outline. For example,

Lighting Market Trend I High Reliability LEDCompetitive Solution Provider for Sulfur Tolerant

High Reliability

Figure 3: The anti-contamination features of the LG Innotek 3030N LEDs produces improved lumen maintenance when exposed to hydrogen sulphide. (Image credit: LG Innotek)


LG Innotek has carried out intensive research to understand the process by which hydrogen sulphide (H2S) and sulphur oxide (SOx) gas contaminates LED lamps, and this underlies the design of its mid-power 3030N LEDs: their package has excellent EMC characteristics, and features silver terminations which are coated to protect them against corrosion (see Figure 3). The 3030N products are valued at approximately 1,000lm/$.

LG is also demonstrating the effectiveness of its design with extended product testing to which standard mid-power LEDs are not subjected. Tested in accordance with the IEC60068-2-43 and IEC60068-2-42 standard, the LEDs’ performance is measured when operating in the presence of air contaminated with sulphur.

Nichia is another LED manufacturer which aims to support the demand for exterior mid-power LEDs, and has done numerous studies on the contamination and oxidation risks affecting its LEDs. Tests based on different classes of corro-sive gas (according to ISO11844), and field tests to measure the increase in mass of the silver elements of the LED attributable to oxidation, led Nichia to develop a new approach to the testing of sulphur contamination: as defined by IEC 60068-2-60, Nichia now performs accelerated testing in a mix of H2S and nitrogen dioxide (NO2) at 40°C and a relative humidity of 75%. All its 757 family devices are tested under these conditions for 240 hours to determine the impact of oxidation and to inform lumen maintenance models.

Lumileds has taken a different approach to solving the problem. Its HR30 (HR stands for ‘High Robustness’) series of LEDs are described by the company as a bridge between high-power and mid-power LEDs in outdoor and industrial applications. They feature a gold-plated lead-frame (eliminating the liability to contamination that mid-power LEDs with a silver leadframe suffer from) and a high-reflectance SMC housing. According to Lumileds, the HR30 devices offer ‘superior corrosion and chemical resistance to all mid-power solutions, including those specially treated for that purpose’. In contrast to high-power LEDs, however, the HR30 devices feature a lower maximum current rating of 240mA. The HR30 devices are valued at between 500lm/$ and 1,000lm/$.

Again, testing in the presence of harsh chemicals demonstrates the robustness of these hardened LEDs. The results shown in Figure 4 are drawn from tests conducted in accordance with the IEC 60068-2-43 method 4 standard, with a 15ppm

Figure 4: Relative colour (CCT) shift in LEDs including the HR30 from Lumileds, tested in air contaminated with H2S. (Image credit: Lumileds)

concentration of H2S in the air at a temperature of 45°C and relative humidity of 75%. Lumileds has also introduced tests performed in the pres-ence of dichlorine (Cl2) gas. The gold leadframe performs well in these tests, whereas silver can react with Cl2 to form silver chloride (AgCl).

Ecosystem Supporting 3030 FormatAs described above, the 3030 format is the favoured package outline supported by manu-facturers of mid-power LEDs for street lighting. To help speed adoption of these 3030 packages, optics manufacturers have developed various arrays which are compatible with street lighting specifications for illuminance, uniformity and glare.

The avoidance of glare is made easier by the use of mid-power LEDs: since they emit less light than high-power LEDs, they need a larger light-emitting surface (LES) for any given illuminance value.

Besides reducing the effect of glare, the optic must also produce the precise beam patterns required in street lighting. LEDiL’s approach has been to match the mechanical dimensions of its STRADA family of optics for street lights that use high-power LEDs. Its STRADELLA family (www.ledil.com/stradella) accommodates the increased number of points of light in a mid-power design, while still producing beam pattern suitable to a streetlight.

Carclo, by contrast, has developed an array specifically for mid-power LEDs. Its 12821 (www.carclo-optics.com/optic-12821?optictype =freeform) product is for an array of 84 mid-power LEDs, and produces a beam pattern suitable for P and S class street lighting. CARCLO has also characterized its street light optics when used with LEDs in the 3030 package.

Driver implementation for mid-power designs should not be difficult. Even though the number of LEDs in a mid-power design is higher, the light manufacturer should be able to use the same driver as for a high-power LED system, using a parallel-series connection between the LEDs. (High-power LEDs are usually connected all in series.)

Mid-power LEDs also give system designers the opportunity to think afresh about the power supply. In some cases an AC-direct solution, in which the power-management circuit is implemented directly on the light engine board, and which offers space and cost savings over a conventional switch-mode power supply, might be a viable choice for street lights.

New LED Choices for Street Light OEMsThere is, then, a new opportunity for manufac-turers of street lights to substantially reduce the BoM cost of their products by using a new generation of hardened mid-power LEDs. Equip-ment designers should, however, bear in mind the optical properties of mid-power LEDs. When producing mid-power LEDs, manufacturers use a cheaper process for phosphor-coating the die than for their high-power LEDs, instead embed-ding the die in a rectangular ‘bath’ of phosphor. This means that the phosphor coating is thicker at the sides than at the centre of the die, resulting in inherent non-uniformity of CCT across the beam. By contrast, high-power LEDs have a coating of a uniform thickness over the entire light-emitting surface, producing an almost perfectly uniform CCT across the entire beam.

In very many street lighting applications, the lumen depreciation attributable to environmental conditions, coupled with any colour shift, will be of negligible concern to specifiers and users. In some high-traffic areas, however, such as city center (downtown) pedestrianised streets, specifiers set very strict criteria for quality of light, and here the use of mid-power LEDs might be inappropriate.

It is also worth noting that street light manufac-turers are looking not only to mid-power LEDs but also to Chip-Scale Package (CSP) LEDs as an alternative to high-power LEDs, in their efforts to improve performance and lifetime and reduce system cost.

Certainly the new generation of hardened mid-power LEDs from Lumileds, LG Innotek and Nichia promises good performance at a much reduced cost compared to high-power LEDs, and looks set to make future street-lighting products more competitive and more attractive to potential buyers.
