The MCP42100 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 MCP42100 has 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 8-pin PDIP and SOIC packages.\n类似型号MCP42100-E/SL, MCP42100-I/SL, MCP42100T-I/SL, MCP42100-E/P, MCP42100-E/ST, MCP42100-I/P, MCP42100-I/ST, MCP42100T-E/ST, MCP42100T-I/ST
