Analog Devices AD7720 Datasheet
The AD7720 sigma‑delta modulator converts analog signals to a high‑speed 1‑bit data stream. It operates from a +5 V supply, accepts differential inputs of 0 V to +2.5 V (or ±1.25 V) and includes an on‑chip 2.5 V reference. The device is offered in a 28‑lead TSSOP package and is rated for –40 °C to +85 °C operation.
Key features include a 12.5 MHz master clock, 16‑bit resolution, 90 dB dynamic range, and low‑power standby mode. Detailed pin functions, timing characteristics, and calibration procedures are provided for designers.
