Analog Devices AD7470/AD7472 Datasheet
The AD7470 (10‑bit) and AD7472 (12‑bit) are high‑speed, low‑power successive‑approximation analog‑to‑digital converters that operate from a single 2.7 V to 5.25 V supply. They achieve up to 1.75 MSPS (AD7470) or 1.5 MSPS (AD7472) while consuming only a few milliwatts, and include an auto‑sleep mode for ultra‑low power at reduced throughput.
The document provides detailed pin‑out diagrams, timing specifications, absolute maximum ratings, and an ordering guide for various SOIC and TSSOP packages. It also describes the reference input requirements, power supply decoupling, and the logic functions of control pins such as CS, RD, CONVST, and BUSY.
