The Microchip MCP4461 is a versatile quad digital potentiometer designed for applications requiring precise resistance adjustment and nonvolatile memory storage. It offers potentiometer or rheostat configurations, a wide range of RAB resistance options (5kΩ, 10kΩ, 50kΩ, 100kΩ), and low wiper resistance. The device incorporates WiperLock™ technology, five general-purpose memory locations, and an I²C serial interface for high-speed read/write operations. With features like hardware and software write protection, and a wide operating voltage range (2.7V to 5.5V), the MCP4461 is ideal for applications such as audio volume control, display calibration, and sensor adjustment.
