    Product Details

    The MAX5427 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that evaluates the MAX5427 digital potentiometer. Included software generates the required signals for one-time-programmable operation and allows easy control of the wiper position. An on-board 8-pin µMAX® socket eases replacement of the device. The EV kit is designed to be connected to a standard IBM®-compatible PC-parallel (printer) port.

    Windows® 95/98/2000-compatible software provides a user-friendly interface to exercise the MAX5427's features. 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.
