Analog Devices AD7682/AD7689 Data Sheet
The AD7682 (4‑channel) and AD7689 (8‑channel) are 16‑bit successive‑approximation register (SAR) analog‑to‑digital converters that operate from a single 2.3 V‑5.5 V supply. They include an internal selectable reference, temperature sensor, one‑pole filter, and optional busy indicator, making them suitable for multichannel, low‑power data‑acquisition systems.
Key features include unipolar, differential and pseudobipolar input configurations, a 250 kSPS maximum conversion rate, low power dissipation (as low as 3.5 mW at 200 kSPS) and operation over –40 °C to +85 °C. The datasheet details pin configurations, timing specifications, absolute maximum ratings, and recommended layout guidelines.
