The MCP4021-202E/SN is a non-volatile, 6-bit digital potentiometer with a resistance of 2.1 kΩ. It features 64 taps controlled through a simple Up/Down (U/D) serial interface and operates on a wide voltage range of 2.7V to 5.5V. The device includes Microchip's WiperLock™ technology to secure the wiper setting in its non-volatile EEPROM memory and offers a typical -3 dB bandwidth of 4 MHz. This potentiometer is designed for an extended temperature range of -40°C to +125°C. It is well-suited for applications such as set point trimming, sensor calibration, and adjustable gain amplifier designs, offering a reliable replacement for mechanical trim pots.
