The MCP4431-104E/ST is a 7/8-bit volatile quad digital potentiometer featuring an I¬=C interface. It offers a quad resistor network with options for potentiometer or rheostat configurations. The device supports a resolution of 7-bit with 128 resistors (129 taps) or 8-bit with 256 resistors (257 taps). Available resistance values include 5 kOc, 10 kOc, 50 kOc, and 100 kOc, with a typical low wiper resistance of 75 Oc. This digital potentiometer operates within a wide voltage range of 1.8V to 5.5V, with specified characteristics from 2.7V to 5.5V. It features low temperature coefficients, with an absolute tempco of 50 ppm and a ratiometric tempco of 15 ppm. The device supports high-speed I¬=C communication at frequencies of 100 kHz, 400 kHz, and 3.4 MHz, and includes a terminal control register for disconnecting resistor network terminals. The MCP4431-104E/ST is designed for extended temperature ranges from -40¬8C to +125¬8C and is available in multiple package types, including 4x4 QFN-20 and TSSOP-20. It also includes features such as brown-out reset protection and internal weak pull-ups on digital inputs, enhancing its reliability in various applications.
