Analog Devices AD7724 Dual Sigma‑Delta Modulator Datasheet
The AD7724 is a dual seventh‑order sigma‑delta modulator that converts analog inputs to a high‑speed 1‑bit data stream. It operates from a 5 V supply, supports both unipolar (0 V to VREF) and bipolar (±VREF/2) input ranges, and includes an on‑chip 2.5 V reference.
The document provides detailed electrical specifications, timing characteristics, pin configurations, and recommended circuit layouts. It also includes performance graphs for signal‑to‑noise ratio, total harmonic distortion, and spurious‑free dynamic range across temperature and frequency ranges.
