Product Introduction

Overview

The AD5648ARUZ-2REEL7 is a low-power, octal, 14-bit, buffered voltage-output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It features an on-chip precision output amplifier that enables rail-to-rail output swing and is available in a 16-lead TSSOP package.
