WMS7204 - 256-TAP QUAD-CHANNEL NON-VOLATILE DIGITAL POTENTIOMETER

Description

The WMS7204 is a 256-tap, quad-channel non-volatile digital potentiometer available in 10KΩ, 50KΩ and 100KΩ end-to-end resistances.

These devices can be used as a three-terminal potentiometer or as a two terminal variable resistor in a wide variety of applications.

Features

  • 256 taps for each potentiometer Four independent, linear-taper channels in one package End-to-end resistance available in 10KΩ, 50KΩ and 100KΩ Selectable output buffer for each channel SPI Serial Interface for data transfer and potentiometer control Daisy-chain operation for multiple devices Nonvolatile storage of four wiper positions per channel with power-on recall.

GENERAL DESCRIPTION The WMS7204 is a 256-tap, quad-channel non-volatile digital potentiometer available in 10KΩ, 50KΩ and 100KΩ end-to-end resistances. These devices can be used as a three-terminal potentiometer or as a two terminal variable resistor in a wide variety of applications. The output of each potentiometer is determined by the wiper position, which varies linearly between VA and VB terminal according to the content stored in the volatile Tap Register (TR).
