MCP4261-502E/ML [Microchip]

The MCP41/426X devices are non-volatile, 8-bit (257 wiper steps) digital potentiometers with EEPROM and 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 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 MCP41/42XX devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count.
