Overview
The AD9763ASTRL, produced by Analog Devices Inc., is a high-speed, dual-port, 2-channel digital-to-analog converter (DAC). This component is part of the AD9763/AD9765/AD9767 family, offering 10-, 12-, or 14-bit resolution. It integrates two high-quality TxDAC+® cores, a voltage reference, and digital interface circuitry into a compact 48-lead LQFP package. The AD9763ASTRL is optimized for processing I and Q data in communications applications, providing exceptional AC and DC performance with update rates up to 125 MSPS.
