The AD7887 datasheet from Analog Devices provides specifications, pin configurations, timing, and performance details for this 12‑bit low‑power ADC.
The AD7887 is a high‑speed, low‑power 12‑bit analog‑to‑digital converter that operates from a single 2.7 V to 5.25 V supply and can achieve a throughput of 125 kSPS. It supports both single‑channel and dual‑channel modes, with an internal 2.5 V reference or an external reference option.
The document includes functional block diagrams, pin descriptions, absolute maximum ratings, timing specifications, power‑down options, and typical performance curves. It also provides an ordering guide, outline dimensions, and automotive‑grade qualification information.
