Product Introduction

Overview

The AD8522ARZ, produced by Analog Devices Inc., is a complete dual 12-bit, single-supply, voltage output Digital-to-Analog Converter (DAC) available in 14-pin plastic DIP and low profile 1.5 mm SOIC-14 packages. Fabricated in a CBCMOS process, this monolithic device is designed for +5 V-only systems, offering low cost and ease of use without requiring any external components to achieve full performance.

The AD8522 features a serial digital interface, onboard reference, and buffered voltage output, making it ideal for various applications that require precise analog voltage outputs from digital inputs.
