Description
General part information
mcp4642 Series
The MCP464X devices are dual channel, non-volatile, 7-bit (129 wiper steps) digital potentiometers with EEPROM and an I2C compatible interface. The MCP464X family is available with end-to-end resistor values of 5KΩ, 10KΩ, 50kΩ and 100KΩ. These devices offer WiperLock™ Technology which allows the user unlimited reprogramming and locking of the wiper setting. It is useful for equipment that requires factory trimming or recalibration. The MCP464X devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count.
