Analog Devices AD7787 Datasheet
The AD7787 is a low‑power, 24‑bit sigma‑delta ADC designed for low‑frequency measurement applications. It features a differential and a single‑ended input, an internal clock, and programmable output rates from 9.5 Hz to 120 Hz. The device operates from a 2.5 V to 5.25 V supply and consumes as little as 75 pA in normal mode and 1 pA in power‑down mode.
Typical applications include smart transmitters, battery monitoring, portable instrumentation, temperature and pressure measurement, and weighing scales. The datasheet provides detailed specifications, timing characteristics, pin descriptions, grounding recommendations, and ordering information.
