The AD7653 is a 16-bit, 1 MSPS, unipolar ADC with an analog input voltage range of 0V to 2.5V, no pipeline delay, and parallel and serial 5V/3V interface compatibility.
The AD7653 is a 16‑bit, 1 MSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers three throughput modes—Warp (1 MSPS), Normal (800 kSPS) and Impulse (666 kSPS)—and includes an internal reference with 7 ppm/°C drift. The device is available in 48‑lead LQFP and 48‑lead LFCSP packages and is rated for operation from –40 °C to +85 °C.
The datasheet provides detailed electrical specifications, timing diagrams for both parallel and serial interfaces, absolute maximum ratings, and pin‑function descriptions. It also includes application hints, layout recommendations, and an ordering guide for the AD7653.
