MCP41HV31 is a single-channel, high voltage digital potentiometer (Digipot) family that supports 10V ~36V or +/-5V to +/-18V power rails. It features 7-bit resolution with SPI interface. This family is available in TSSOP-14 and QFN-20 (5x5) packages and has 5kΩ, 10 kΩ, 50 kΩ, and 100 kΩ end-to-end resistance(RAB) options . All parts are guaranteed to operate over  –40°C to +125°C extended temperature range.

Microchip's MCP41HVX1 and MCP45HVX1 digital potentiometer (Digipot) families offer the widest operating voltage range that is currently available on the market.
