Product Introduction

Overview

The AD8804ARUZ from 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 TSSOP package and is ideal for replacing mechanical trimmers in new designs. It is particularly suited for dc voltage adjustment applications and can be easily programmed via a 3-wire SPI-compatible serial interface. The AD8804ARUZ offers features such as power shutdown, separate VREFL input for maximizing resolution, and low power consumption, making it versatile for various electronic systems.
