ADNS-8020
Data Sheet
Description
The ADNS-8020 is the Track-on-Glass Laser navigationsensor empowered by PixArt Imaging that enablesnavigation on all surface types including glass. It is capable of sensing mouse motion with velocities up to 30 inches per second (ips) on non-glass surfaces, 10 inches per second (ips) on glass and acceleration up to 8g.
The ADNS-8020 has dual power supplies of 1.8V and 3.0V, which enables wireless application to lengthen battery life. It integrates both sensor and VCSEL chips in a single 16-pin molded lead-frame DIP package. It is designed to be used with ADNS-8100-002 lens to form a complete la-ser illuminated navigation system. These parts provide a complete and compact navigation system without mov-ing parts and laser calibration process is NOT required in the complete mouse form, thus facilitating high volume assembly. Performance is not guaranteed if the ADNS-8020 sensor is paired with a lens other than the ADNS-8100-002. Additionally, performance is not guaranteed if the ADNS-8100-002 lens is used in conjunction with a dif-ferent navigation sensor other than the ADNS-8020.
Theory of Operation
The sensor is based on Track-on-Glass and Laser technologies, which measure changes in position by op-tically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a four wire se-rial port. The IAS acquires microscopic surface images via the lens and illumination system provided by the VCSEL. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the Δx and Δy relative displacement values. An external mi-crocontroller reads the Δx and Δy data information from the sensor serial port, then translates the data into USB or RF signals before sending them to the host PC or game console.

Note: This sensor is designed to work on glass with a thickness of at least 5mm. Most glass surfaces provide enough microscopic features to allow tracking. It will not work on glass that is perfectly clean and virtually scratch-free.The minimum requirements for the sensor to work reliably on glass is there must be at least 50 features/mm2 at the minimum of 6 μm width and 2 μm depth.
