The MCP4361 devices are non-volatile, 6-bit (257 wiper steps) digital potentiometers that are programmed/reprogrammed through an SPI compatible interface. The MCP4361 devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count. These devices offer WiperLock Technology which allows the user unlimited reprogramming and locking of the wiper setting. This is useful for equipment that requires factory trimming or recalibration. The MCP4361 family of devices are available with resistor values of 5K, 10K, 50k and 100K.
