AD5222 - Increment/Decrement Dual Digital Potentiometer

Datasheet Summary

Description

The AD5222 provides a dual channel, 128-position, digitally controlled variable-resistor (VR) device.

This device performs the same electronic adjustment function as a potentiometer or variable resistor.

These products were optimized for instrument and test equipment push-button applications.

Features

  • 128-Position, 2-Channel Potentiometer Replacement 10 k⍀ , 50 k⍀ , 100 k⍀, 1 M⍀ Very Low Power: 40 ␮A Max ؎ 2.7 V Dual Supply Operation or 2.7 V to 5.5 V Single Supply Operation Increment/Decrement Count Control.
