Product Introduction

Overview

The AD9755ASTRL, produced by Analog Devices Inc., is a dual, muxed port, ultra-high-speed, single-channel, 14-bit CMOS Digital-to-Analog Converter (DAC). It integrates a high-quality 14-bit TxDAC+ core, a voltage reference, and digital interface circuitry into a compact 48-lead LQFP package. This DAC is optimized for ultra-high speed applications, supporting update rates up to 300 MSPS, making it suitable for demanding environments where high data rates are required.
