19-1896; Rev 0; 1/01 256-Tap, µPoT, Low-Drift, Digital Potentiometer General Description 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. This device also provides glitchless switching between resistor taps, as well as a convenient power-on reset (POR) that sets the wiper to the midscale position at power-up. A low 5ppm/°C ratiometric temperature coefficient makes it ideal for applications requiring low drift.
