MCP42100

The MCP42100 digital potentiometer features two independent channels, 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 MCP42100 has a resistance value of 100 kohm, outstanding AC and DC characteristics, and consumes <1 A during static operation. Applications for the MCP42100 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 MCP42100 is available in 14-pin PDIP, SOIC and TSSOP packages.
