The AD7865 is a 14‑bit analog‑to‑digital converter that samples four channels simultaneously from a single 5 V supply. It offers selectable input ranges (±10 V, ±5 V, ±2.5 V, 0‑2.5 V, 0‑5 V), a 2.4 µs conversion time, and a high‑speed parallel data bus for easy connection to microprocessors.
The document provides detailed specifications, pin configurations, timing characteristics, absolute‑maximum ratings, and ordering information. It also includes ESD handling guidelines and a functional block diagram to aid designers in integrating the AD7865 into low‑power, high‑speed data‑acquisition systems.
