Analog Devices AD7899 14‑Bit ADC Datasheet
The AD7899 is a 14‑bit successive‑approximation analog‑to‑digital converter that operates from a single 5 V supply and consumes as little as 80 mW typical. It features a 2.2 µs conversion time, 400 kSPS maximum throughput, and a high‑speed parallel data bus that can interface with 3 V or 5 V processors.
The device supports multiple input voltage ranges (±10 V, ±5 V, ±2.5 V, 0‑2.5 V, 0‑5 V) with built‑in over‑voltage protection, an internal 2.5 V reference, and optional external clocking. Pin‑out, timing characteristics, and ordering information are provided for system integration. This manual is written in Chinese.
