Component List
General DescriptionThe MAX5216DACLite evaluation kit (EV kit) enables evaluation of the MAX5216 single-channel, low-power, buffered-output, 3-wire SPI interface, 16-bit DAC. The EV kit also includes Windows XPM-, Windows VistaM-, and
WindowsM 7-compatible software that provide a simple graphical user interface (GUI) for exercising the features of the IC.The EV kit enables a quick evaluation of the device, with a fixed supply voltage of 3.3V. The EV kit allows for the generation of selectable waveforms to display DAC AC signal-generation capability.The EV kit can be used as a system hardware debugging tool, or as a signal generator demonstration kit.

ProcedureTheEVkitisfullyassembledandtested.Followthestepsbelow to verify board operation:1) Visit www.maximintegrated.com/evkitsoftware to
download the latest version of the EV kit software, 5216DACLiteRxx-LV.ZIP. Unzip the file and run thesetup.exe.Followtheinstructionstoinstalltheevalua-tion software on your PC. The program files are copied and icons are created in the Windows Start | Programs menu. Connect the MAX5216DACLite to the PC though aUSBcable.Noadditionaldriverisneeded;Windowsrecognizes the new device as a human interfacedevice (HID) and automatically finds and installs theappropriate driver for it. Formore information, checkthe device properties in: Device Manager\Human Interface Control\USB Input Device\Properties → USB\VID_0B6A&PID_1234.SeeFigure1.

Detailed Description of SoftwareSingle Operation TabThe Single Operation tabsheet (Figure2) isactivebydefault. The application checks all the boards with the USBVID/PID0x0B6A/0x1234 thatconnected to thePCand indicates them on the right side of the GUI. Up to 16 boards can be connected to the system. Each board has its own unique board index. Select the appropriate board index in the Board Indexspinbox(Figure3).Any possible operation can be evaluated on this tab sheet.Forexample,movethetrackbarslider toset theDAC output voltage. The DAC Control spin box reflects the slider position with a decimal number. Connect the DMM to the J5 header (Figure 8) tomeasure theDACoutput voltage.
The DAC output can also be set by typing in a decimal, hexadecimal, or an octal or binary value in the DAC Controlspinbox(Figure4).TheICacceptscodesfrom0 to65535 (216-1)decimalor from0 toFFFFhex.Thenotation is displayed on the left side of the box.The Rising Ramp, Falling Ramp, Triangle, Sine, Square wave, or Staircase tab sheets give the DAC the ability to generate different waveforms with the selected parameters (see the sine-wave and staircase plots in Figures5and6).Thereisapossibledelaytostartanewwaveform until the previous one finishes a full cycle when switching between tabs.

Detailed Description of HardwareThe MAX5216DACLite EV kit board is loaded with the MAX5216, Maxim’s best-in-class, lowest power, 16-bit DAC.Theon-boardMAX6133A30provideslownoise,lowtemperaturedriftof3ppm/°C,and3.000Vprecisevoltagereference for the DAC. The MAX5216 (U1) receives a commandfromthe16-bitMAXQ622microcontroller(U2)through a 3-wire high-speed SPI bus. The U1 device can run at 50MHz clock frequency, but the SPI bus speedis limited to 6MHz on this board by themicrocontroller.TheU1–U3devicesarepoweredbytheMAX8510+3.3VLDO,low-noisevoltageregulator(U4),whichgetspowerfrom theUSBport.TheU1device canbeevaluatedatthe fixed VDD level of 3.3V only. The above limitations are reflected by the suffix “Lite” in the name of the board. The EVkitblockdiagramisshowninFigure7.

The evaluation software allows full access to the DAC’s functions and features through the full-speed USB 2.0bus and the U2 microcontroller. The microcontroller is preloaded with firmware that communicates with the GUI.
MAX5216Lite Extended FeaturesThe U1 device can be evaluated over the full voltage and SPI bus speed range with external power supply and SPI host controller. To do so, the following board modifications must be made:1) Totally disconnect the U1 and U3 devices from the rest
oftheboardbyremovingresistorsR4–R9(seeFigure10for component placement).
2) Connect the SPI lines (CSb, SCLK,DIN, andCLRbpins)fromJ6totheexternalhostcontroller.Makesurethat the input voltage (VIH) is within the spec limit and matches the AVDD level.
3) Applyexternalpowerfrom2.7Vto5.5VbetweenJ3.2(AVDD)andJ8(GND).
4) Send command to the DAC.
The microcontroller on the EV kit board can also be programmedwithcustomfirmwarethroughtheJ2JTAGconnector (see Table 1).
