Product Overview

The MCP4161-502E/P is a 7/8-bit Single/Dual SPI Digital Potentiometer with non-volatile memory. The MCP41/424X 8-bit (257 wiper steps) digital potentiometer comes with an EEPROM and SPI compatible interface. This device offers 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.
  • 8-bit: 256 resistors with taps to VSS and VDD
  • SPI compatible interface
  • Automatic recall of potentiometer wiper settings
  • 5, 10, 50 and 100kΩ Resistance values
  • Low Tempco
  • 100Ω Typical low wiper resistance
  • WiperLock™ technology to secure the EEPROM
  • Low-power operation - 1µA maximum static current
