This product is a 10-bit, 300 MSPS high speed TxDAC+® D/A converter
The AD9751 is a dual‑muxed‑port, ultrahigh‑speed 10‑bit CMOS DAC designed for applications requiring up to 300 MSPS update rates. It integrates a high‑quality TxDAC+ core, on‑chip 1.20 V band‑gap reference, and digital interface circuitry in a 48‑lead LQFP package. The device supports both differential and single‑ended clock inputs and offers flexible digital interfacing via two buffered latches.
Key specifications include a 10‑bit resolution, 300 MSPS maximum output update rate, 155 mW power dissipation at 3.3 V, and a full‑scale output current of 20 mA. The AD9751 operates from a 3.0‑3.6 V supply range and is suited for high‑speed communications, digital synthesis, and QAM/OFDM applications.
