Evaluates: MAX5216 MAX5216DACLite Evaluation Kit
www.maximintegrated.com
The evaluation software allows full access to the DAC’s
functions and features through the full-speed USB 2.0
bus and the U2 microcontroller. The microcontroller is
preloaded with firmware that communicates with the GUI.
MAX5216Lite Extended Features
The 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
oftheboardbyremovingresistorsR4–R9(seeFigure10
for component placement).
2) Connect the SPI lines (CSb, SCLK, DIN, and CLRb
pins)fromJ6totheexternalhostcontroller.Makesure
that the input voltage (V
IH
) is within the spec limit and
matches the AVDD level.
3) Applyexternalpowerfrom2.7Vto5.5VbetweenJ3.2
(AVDD)andJ8(GND).
4) Send command to the DAC.
The microcontroller on the EV kit board can also be
programmedwithcustomfirmwarethroughtheJ2JTAG
connector (see Table 1).
