Analog Devices AD7908/AD7918/AD7928 Datasheet Rev D
The AD7908/AD7918/AD7928 family are 8‑channel successive‑approximation ADCs with 8‑, 10‑, and 12‑bit resolutions respectively. They operate from a single 2.7 V to 5.25 V supply and achieve up to 1 MSPS throughput. Each part includes a channel sequencer for programmable conversion order and a low‑noise track‑and‑hold front‑end capable of handling input frequencies above 8 MHz.
Key features include low power consumption (6 mW at 3 V, 13.5 mW at 5 V), automotive qualification, flexible serial‑clock management, multiple serial interfaces (SPI, QSPI, Microwire, DSP compatible), and a shutdown mode drawing as little as 0.5 pA. The document details electrical specifications, pin configurations, and application hints for microprocessor integration.
