The MCP4451-104E/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), and it is available in four resistance values: 5 kOc, 10 kOc, 50 kOc, and 100 kOc. This digital potentiometer has a low wiper resistance of 75 Oc typical and operates over a wide voltage range of 1.8V to 5.5V, with specified characteristics from 2.7V to 5.5V. It features a low temperature coefficient, with absolute values at 50 ppm typical and ratiometric values at 15 ppm typical. The device supports high-speed I¬=C communication at frequencies of 100 kHz, 400 kHz, and 3.4 MHz, allowing for efficient read/write operations to the wiper. The MCP4451-104E/ST includes a terminal control register for resistor network terminal disconnection, a reset input pin, and brown-out reset protection at 1.5V typical. It is designed for extended temperature ranges from -40¬8C to +125¬8C and is available in multiple package types, including TSSOP-20 and QFN-20. This product is suitable for applications requiring precise resistance adjustments and digital control in various electronic designs.
