Microchip Technology, Inc. Digital Potentiometers MCP4231T-104E/ST

The MCP4231T-104E/ST is a dual-channel digital potentiometer featuring a 7-bit resolution with 128 resistor steps. It operates via a Serial Peripheral Interface (SPI) with a maximum clock speed of 10 MHz, allowing for high-speed read and write operations. The device supports a wide operating voltage range from 1.8V to 5.5V and is specified for an extended temperature range of -40¬8C to +125¬8C. This digital potentiometer offers resistor network configurations as either potentiometer or rheostat, with resistance options of 5 k,Ѷ, 10 k,Ѷ, 50 k,Ѷ, and 100 k,Ѷ. It has a low wiper resistance of 75,Ѷ and features a brown-out reset protection at 1.5V. The MCP4231T-104E/ST is suitable for applications requiring precise resistance adjustments and can be used in split rail applications. The device also includes a shutdown pin for terminal disconnect and has low quiescent current consumption, making it efficient for battery-powered applications.
