AD8403 - 2-Channel/ 256-Position Digital Potentiometer

General Description

The AD8400/AD8402/AD8403 provide a single-, dual-, or quad-channel, 256-position, digitally controlled variable resistor (VR) device.1 These devices perform the same electronic adjustment function as a mechanical potentiometer or variable resistor.

Key Features

  • 256-position variable resistance device Replaces 1, 2, or 4 potentiometers 1 kΩ, 10 kΩ, 50 kΩ, 100 kΩ Power shutdown.
  • less than 5 μA 3-wire,SPI-compatible serial data input 10 MHz update data loading rate 2.7 V to 5.5 V single-supply operation Qualified for automotive.
