Analog Devices AD7927 Datasheet Rev C
The AD7927 is a high‑speed, low‑power, 12‑bit successive‑approximation ADC with eight single‑ended inputs and a channel sequencer. It operates from a single 2.7 V to 5.25 V supply and provides up to 200 kSPS throughput.
The device includes a flexible serial interface (SPI, QSPI, Microwire), shutdown modes for power saving, and is qualified for automotive applications. Detailed specifications, pin descriptions, timing diagrams, and ordering information are provided in the document.
