This document is the AD7699 data sheet, which introduces the features of the AD7699, including 16-bit resolution, 8-channel multiplexer, 500kSPS throughput, ±0.5LSB typical error, 93.3dB dynamic range, 91.5dB SINAD, -97dB THD
The AD7699 is an 8‑channel, 16‑bit successive‑approximation register (SAR) analog‑to‑digital converter that operates from a single 5 V supply. It integrates a low‑drift internal reference, temperature sensor, selectable one‑pole filter, and channel sequencer for multichannel data‑acquisition systems.
The datasheet provides detailed specifications, pin descriptions, timing diagrams, layout recommendations, and application hints for designing low‑power, high‑accuracy measurement hardware.
