The MAX5427 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that evaluates the
MAX5427 digital potentiometer. Included software gener-
ates the required signals for one-time-programmable
operation and allows easy control of the wiper position.
An on-board 8-pin µMAX

standard IBM-compatible PC-parallel (printer) port.
Windows
user-friendly interface to exercise the MAX5427’s fea-
tures. The program is menu driven and offers a graphic
user interface with control buttons. (Note: Windows 2000
requires the installation of a driver; refer to Win2000.pdf
or Win2000.txt located on the diskette for information.)
This EV kit can also be used to evaluate the MAX5428
and MAX5429 digital potentiometers.
