MCP4XXXDM-DB MCP4XXX Digital Potentiometer Daughter Board

The MCP4xxx Digital Potentiometer Daughter Board allows the system designer to quickly evaluate the operation of Microchip Technology’s MCP42XXX and MCP402X Digital Potentiometers. The MCP42XXX are dual Digital Potentiometer devices that have the same characteristics as their single Digital Potentiometer devices (MCP41XXX). The MCP402x devices are non-volatile devices that have similar characteristics as their volatile memory versions (MCP401X). The board supports two MCP42XXX devices to allow the Resistor Networks to be “stacked” and form a programmable windowed Digital Potentiometer and an MCP402X device, which can be replaced with an MCP401X device. The board has one MCP42010 device (10 kΩ), which can be the rheostats at the ends, and one MCP42010 device (10 kΩ) which is the potentiometer in the middle and a separate standalone potentiometer.

The board also has a voltage doubler device (TC1240A), which can be used to show the WiperLock Technology feature of the MCP4021.

The MCP4XXX Digital Potentiometer Daughter Board has been made configurable, via jumpers. This allows you to determine the configuration that you wish to have the four digital potentiometer of the MCP42XXX devices.
