Product Introduction

Overview

The AD5348BRUZ is a digital-to-analog converter (DAC) produced by Analog Devices Inc. It is part of the AD5346/AD5347/AD5348 family, specifically being an octal 12-bit DAC. This device operates from a supply voltage range of 2.5 V to 5.5 V and features an on-chip output buffer that can drive the output to both supply rails. The AD5348BRUZ also allows a choice of buffered or unbuffered reference inputs, making it versatile for various applications.
