WMS7171 - (WMS7170 / WMS7171) NON-VOLATILE DIGITAL POTENTIOMETERS

Download the WMS7171 datasheet PDF. This datasheet also covers the WMS7170 variant, as both devices belong to the same (wms7170 / wms7171) non-volatile digital potentiometers family and are provided as variant models within a single manufacturer datasheet.

Description

The WMS7170/7171 is a single channel 100-tap non-volatile linear digital potentiometer available in 10KΩ, 50KΩ and 100KΩ resistance.

The device consists of Up/Down serial interface, tap register, decoder, resistor array, wiper switches, NV memory and control logics.

Features

  • Drop-in replacement for many popular parts Single linear-taper channel 100 taps 10K, 50K and 100K end-to-end resistance VSS to VDD terminal voltages Automatic recall of wiper position when power-on Potentiometer control through Up/Down (3-wire) serial interface Endurance 100,000 cycles Data retention 100 years Package options: 8-pin PDIP, SOIC or MSOP Industrial temperature ran.
