Device Overview

Summary

The MCP41100 is a single-channel, 8-bit digital potentiometer features 100kΩ end-to-end resistance value with an SPI serial interface. The wiper position varies linearly and is controlled via the SPI interface. The MCP41100 has outstanding AC and DC characteristics, and consumes <1 µA during static operation. Applications for the MCP41100 digital potentiometer include audio equipment (volume and tone controls), servo-motor control, battery charging and control, communications (line impedance matching), power supplies, instrumentation (gain, offset adjust), LCD contrast control and programmable filters. The MCP41100 is available in 8-pin PDIP and SOIC packages.

MCP4XXX Digipot Daughter Board
MCP4XXX Digipot Daughter Board ( MCP4XXXDM-DB )

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...
