Description

The MCP41100 single-channel digital potentiometer features 8-bit resolution (256 wiper steps), and an industry-standard SPI serial interface. The wiper position varies linearly and is controlled via the SPI interface. The MCP41100 has a resistance value of 100 kohm, outstanding AC and DC characteristics, and consumes <1 A 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.
