AD9780/AD9781/AD9783 are LVDS interface DACs with 12/14/16-bit 500MSPS, high dynamic range, low noise and intermodulation distortion, single carrier W-CDMA ACLR reaches [email protected] IF.
The AD9780, AD9781, and AD9783 are pin‑compatible, high‑dynamic‑range dual DACs offering 12‑, 14‑, or 16‑bit resolution and up to 500 MSPS sample rates. They feature low noise, programmable differential current outputs, auxiliary 10‑bit DACs, and an internal 1.2 V precision reference, operating from 1.8 V and 3.3 V supplies.
The handbook includes feature tables, application examples, functional block diagrams, detailed specifications (DC, digital, AC), absolute maximum ratings, thermal resistance data, ESD precautions, and full pin‑out descriptions for each device variant.
