Product Introduction

Overview

The AD5318ARU, produced by Analog Devices Inc., is a 10-bit octal voltage output Digital-to-Analog Converter (DAC) packaged in a 16-lead TSSOP. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes a typical current of 0.7 mA at 3 V. It features on-chip output buffer amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/μs. The AD5318 is part of a family that includes 8-bit and 12-bit versions, offering flexibility in resolution selection without requiring circuit redesign.
