Analog Devices AD7694 16‑Bit PulSAR® ADC Data Sheet
The AD7694 is a 16‑bit charge‑redistribution successive‑approximation ADC that operates from a single supply (2.7 V‑5.25 V). It offers 250 kSPS throughput at 5 V, no missing codes, and a proprietary SPI‑compatible serial interface. The device is housed in an 8‑lead MSOP package and is specified for –40 °C to +85 °C operation.
The datasheet provides detailed specifications, timing diagrams, pin descriptions, recommended driver amplifiers, layout guidelines, and typical performance graphs. It also includes ordering information and an evaluation board reference for system designers.
