Analog Devices AD7911/AD7921 Datasheet
The AD7911 and AD7921 are dual‑channel successive‑approximation ADCs offering 10‑bit (AD7911) or 12‑bit (AD7921) resolution, up to 250 kSPS throughput, and a supply range of 2.35 V to 5.25 V. They feature low‑power operation, a wide‑band track‑and‑hold amplifier, and flexible serial‑clock management compatible with SPI, QSPI, Microwire and DSP interfaces.
The datasheet provides full electrical specifications, absolute maximum ratings, pin‑out diagrams, timing diagrams, typical performance curves, conversion operation details, and an ordering guide. Application hints, grounding and layout recommendations, and power‑vs‑throughput charts help designers integrate the parts into battery‑powered systems, instrumentation, communications, and data‑acquisition designs.
