Product Introduction

Overview

The AD7247JNZ, produced by Analog Devices Inc., is an enhanced version of the industry-standard AD7247. This component is a complete, dual 12-bit, voltage output digital-to-analog converter (DAC) with integrated output amplifiers and a Zener voltage reference on a single monolithic CMOS chip. It is designed to offer improved performance with faster interface times, better reference variations, and faster settling times compared to its predecessors. The AD7247JNZ is microprocessor compatible and features high-speed data latches and interface logic, making it suitable for a wide range of applications requiring precise analog output from digital inputs.
