Product Introduction

Overview

The AD9764ARU, produced by Analog Devices Inc., is a 14-bit resolution member of the TxDAC series of high-performance, low-power CMOS digital-to-analog converters (DACs). This device is specifically optimized for the transmit signal path of communication systems and offers exceptional AC and DC performance. It supports update rates up to 125 MSPS and operates on a flexible single-supply range of 2.7 V to 5.5 V, making it well-suited for portable and low-power applications.
