The MAX9939 evaluation kit (EV kit) is a fully assembled

and tested surface-mount PCB that evaluates the

MAX9939 SPI™-programmable gain amplifier (PGA). Its

internal op amp is configured as a multiple-feedback

active filter by default, but can also be reconfigured so

the MAX9939 operates as a differential-input, differen-

tial-output programmable gain amplifier. The EV kit fea-

tures an on-board microcontroller, which receives

commands from a PC through the USB port. The EV kit

can be powered directly from the USB bus or from a

single-supply voltage of 2.9V to 5.5V.

The EV kit also includes Windows

Windows Vista

simple user interface for exercising the MAX9939 fea-

tures. The program is menu driven and offers a graphical

user interface (GUI) complete with control buttons and

status displays. The GUI demonstrates the programma-

ble gains from 0.2V/V to 157V/V and the input offset volt-

age compensation features of the MAX9939 IC.
