MCP4631

The MCP463X devices are dual channel, volatile, 7-bit (257 wiper steps) digital potentiometers with an I2C compatible interface. The MCP463X family is available with end-to-end resistor values of 5KΩ, 10KΩ, 50kΩ and 100KΩ. These devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count.
