This document introduces AD9444, a 14-bit, 80 MSPS A/D converter with guaranteed 80 MSPS sampling rate, 100 dB two-tone SFDR, 73.1 dB SNR, 97 dBc SFDR, excellent linearity (DNL = ±0.4 LSB typical, INL = ±0.6 LSB typical), 1.2 W power dissipation, 3.3 V and 5 V supply operation, 2.0 V p-p differential full-scale input, LVDS outputs (ANSI-644 compatible), data format select, output clock available
The AD9444 is a 14‑bit, 80 MSPS analog‑to‑digital converter optimized for power, size, and ease of use. It includes an on‑chip track‑and‑hold circuit, supports LVDS or CMOS outputs, and operates from 3.3 V and 5.0 V supplies without external reference components.
The document lists detailed DC, AC, digital, and switching specifications, absolute maximum ratings, ESD precautions, mechanical dimensions, and ordering information for the 100‑lead TQFP/EP package.
