Product Introduction

Overview

The AD8804ARZ-REEL, produced by Analog Devices Inc., is a 12-channel, 8-bit TrimDAC (digital-to-analog converter) designed to provide independent digitally-controllable voltage outputs. This component is housed in a compact 20-lead SOIC package, making it ideal for applications requiring multiple voltage adjustments in a small footprint. The AD8804 is particularly useful for replacing mechanical trimmers in new designs and is easily programmable via a 3-wire SPI-compatible serial interface.
