MCP4252

The MCP41/425X devices are volatile, 8-bit (257 wiper steps) digital potentiometers with an SPI compatible interface. The MCP41/42XX 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.
