Product Introduction

Overview

The AD8403ARZ50-REEL, produced by Analog Devices Inc., is a 4-channel digital potentiometer that offers a versatile and programmable solution for various electronic adjustment needs. This device is part of the AD8400/AD8402/AD8403 series, which provides single-, dual-, or quad-channel digitally controlled variable resistors. The AD8403 specifically contains four independent variable resistors, each with 256 programmable positions, making it an ideal replacement for mechanical potentiometers or variable resistors.

The device operates over an extended industrial temperature range of -40°C to +125°C and supports single-supply operation from 2.7 V to 5.5 V. It features a 3-wire SPI-compatible serial data input and a high update data loading rate of 10 MHz. The AD8403 is available in various packages, including 24-lead PDIP, SOIC, and TSSOP, making it suitable for a wide range of applications.
