256-Tap SOT-PoT, Low-Drift Digital Potentiometers in SOT23
General Description
The MAX5400/MAX5401 digital potentiometers offer 256-tap SOT-PoT™ digitally controlled variable resistors in tiny 8-pin SOT23 packages. Each device functions as a mechanical potentiometer, consisting of a fixed resistor string with a digitally controlled wiper contact. They operate from +2.7V to +5.5V single-supply voltages and use an ultra-low supply current of 0.1µA. These devices also provide glitchless switching between resistor taps, as well as a convenient poweron reset that sets the wiper to the midscale position at power-up. A low 5ppm/°C ratiometric temperature coefficient makes...
