Overview
The AD9751ASTZ, produced by Analog Devices Inc., is a dual muxed port, ultrahigh speed, single-channel, 10-bit CMOS Digital-to-Analog Converter (DAC). This device integrates a high-quality 10-bit TxDAC+ core, a voltage reference, and digital interface circuitry into a compact 48-lead LQFP package. It is designed for ultrahigh speed applications, supporting update rates up to 300 MSPS, making it ideal for scenarios where data rates exceed those possible on a single data interface port DAC.
