Analog Devices AD7716 Datasheet
The AD7716 is a 4‑channel 22‑bit A/D converter designed for low‑frequency, high‑dynamic‑range measurements such as ECG, EEG, and other biomedical or process‑control signals. It features on‑chip digital filtering with selectable cutoff frequencies of 584 Hz down to 36.5 Hz and provides a usable dynamic range up to 105 dB.
The device is supplied in 44‑pin PQFP or PLCC packages, operates from ±5 V supplies, and includes a serial interface with pins for address, cascade, and data control. Typical applications include biomedical data acquisition, high‑accuracy instrumentation, and seismic systems.
