MAX5400 - 256-Tap SOT-PoT / Low-Drift Digital Potentiometers in SOT23

Datasheet Summary

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.

19-1848; Rev 0; 10/00 256-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 it ideal for applications requiring low drift.
