Analog Devices AD9444 14‑Bit 80 MSPS ADC Datasheet Rev 0
The AD9444 is a 14‑bit monolithic sampling ADC optimized for low power, small size, and ease of use. It operates up to 80 MSPS and supports both LVDS‑compatible (ANSI‑644) and CMOS output formats. The device requires 3.3 V and 5.0 V supplies and a low‑voltage‑differential input clock.
The datasheet provides detailed electrical specifications, pin configurations, timing diagrams, and evaluation board schematics. It also includes absolute maximum ratings, thermal information, and ordering details for the 100‑lead TQFP/EP package.
