AD7683 is a 16-bit, 100 kSPS, single-ended PulSAR ADC in MSOP/QFN package.
The AD7683 is a 16‑bit, charge‑redistribution, successive‑approximation PulSAR® analog‑to‑digital converter. It operates from a single power supply (2.7 V‑5.5 V) and provides a serial SPI‑compatible interface. The device offers no missing codes, low power consumption, and a wide input range (0 V‑VREF).
The datasheet includes specifications, timing diagrams, pin descriptions, layout recommendations, and typical performance graphs. It also provides an ordering guide for the MSOP and QFN package options.
