Microchip MCP4021/2/3/4 Digital Potentiometer Datasheet
The MCP4021/2/3/4 family are low‑cost, non‑volatile 6‑bit digital potentiometers that can be configured as either a potentiometer or a rheostat. They use a simple Up/Down serial interface and incorporate Microchip's WiperLock technology to store calibration settings in EEPROM without a separate write‑protect pin.
Key specifications include a wide operating voltage range of 2.7 V to 5.5 V, 64 taps (63 resistors), high‑voltage tolerant digital inputs up to 12.5 V, and low‑power static current of 1 pA. The devices are offered in SOT‑23‑6, SOIC, MSOP, and DFN packages and are suitable for power‑supply trimming, calibration, and mechanical potentiometer replacement applications.
