The AD7904, AD7914, and AD7924 are 8‑, 10‑, and 12‑bit, 4‑channel successive‑approximation ADCs that operate from a single 2.7 V to 5.25 V supply. They feature a channel sequencer, low‑power operation, and a high‑speed SPI/QSPI/MICROWIRE serial interface.
The datasheet provides detailed electrical specifications, timing diagrams, power‑management modes, and layout recommendations for optimal analog and digital performance. It also includes application hints for interfacing the devices to DSPs and microcontrollers.
