Product Introduction

Overview

The AD5348BRU-REEL7 is a 12-bit octal digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a 2.5 V to 5.5 V supply and is designed for a wide range of applications requiring high precision and reliability. The AD5348 features a parallel interface, allowing for simultaneous update of all DAC outputs via the LDAC pin, and includes an on-chip output buffer that can drive the output to both supply rails.
