MCP41U83 (Single) and MCP42U83 (Dual) Potentiometers

Microchip MCP41U83 and MCP42U83 are 7-bit digital potentiometers offering 128 wiper positions and integrated EEPROM for non-volatile storage of wiper settings. These devices are designed for applications requiring precise analog control with digital programmability, such as calibration, gain adjustment, and offset trimming.

Both devices support SPI communication up to 10 MHz and operate over a wide voltage range of 1.8 V to 5.5 V, making them suitable for both low-power and standard embedded systems. The MCP41U83 features a single potentiometer channel, while the MCP42U83 provides two independently controlled channels. The EEPROM allows the wiper position to be retained across power cycles, reducing the need for reinitialization at startup.
