The AD9786 is a 16-bit, 200 MSPS/500 MSPS TxDAC+® with 2×/4×/8× interpolation and signal processing capabilities. It features high resolution, low distortion, low noise, and a flexible calibration engine.
The AD9786 is a 16‑bit CMOS digital‑to‑analog converter designed for communications applications such as multicarrier base stations and RF signal generators. It offers selectable interpolation filters (2×, 4×, 8×) and multiple modulation modes, providing flexible clock and data interfaces.
The device operates from 3.1‑3.5 V analog supply and 2.5 V digital supplies, delivering a full‑scale output current of 10‑20 mA. It includes an on‑chip 1.20 V reference, a comprehensive calibration engine, and supports multichip synchronization for master‑slave configurations.
