MCP4XXXDM-DB

The MCP4XXXDM-DB is a MCP4xxx digital potentiometer daughter board allows the system designer to quickly evaluate the operation of 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 (10kΩ), which can be the rheostats at the ends, and one MCP42010 device (10kΩ) 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.

• MCP4XXXDM-DB allows to quickly evaluate the operation of MCP42XXX and MCP402X digital potentiometers
• Header interface to PICDEM boards using 28 pin header
• TC1240A voltage doubler to generate VIHH voltage for wiperlock technology evaluation
• Jumpers for MCP4021 Pot (A, W, and B) to replace U1 Pot0 in desired circuit
• Pads for easy connection to the digital potentiometer signals
• Jumpers for routing signals from either a PICDEM HPC demo board or a PICDEM FS USB demo Board
• Jumpers for configuration of U1 Pot0, U2 Pot0, and U2 Pot1 terminal connections
