概述
Description
The AD7680BRM is Analog Devices’ high‑resolution ADC (16‑bit) with a serial SPI‑style interface. It uses a SAR architecture with an integrated sample/hold and supports unipolar or bipolar input ranges, making it suitable for instrumentation and data‑acquisition tasks. It can operate from a single supply and offers options for internal or external references, with a 16‑bit output word via the serial interface. The BRM suffix indicates a compact package variant. Typical applications include test equipment, process monitoring, and portable instrumentation requiring precise, mid‑speed conversions. For exact specs—full‑scale range, input bandwidth, conversion speed, power, and reference options—refer to the official AD7680 datasheet.
