MAX5402 Overview
The MAX5402 µPoT™ digital potentiometer is a 256-tap variable resistor with 10kΩ total resistance in a tiny 8pin µMAX package. This device functions as a mechanical potentiometer, consisting of a fixed resistor string with a digitally controlled wiper contact. It operates from +2.7V to +5.5V single-supply voltages and uses an ultra-low 0.1µA supply current.
