This datasheet provides detailed information on the AD7927, including features, specifications, pins, and package.
The AD7927 is a high‑speed, low‑power, 8‑channel successive‑approximation ADC that operates from a single 2.7 V to 5.25 V supply. It offers up to 200 kSPS throughput, a 12‑bit resolution, and a wide input bandwidth suitable for frequencies above 8 MHz.
Key features include eight single‑ended inputs with a programmable channel sequencer, multiple serial interfaces (SPI, QSPI, Microwire), shutdown modes for power saving, and a conversion time as short as 800 ns when driven by a 20 MHz serial clock.
