Analog Devices AD7400 Datasheet
The AD7400 is a second‑order sigma‑delta modulator with on‑chip digital isolation. It operates from a 4.5 V to 5.25 V supply, offers a 10 MHz clock rate, and delivers a 16‑bit resolution with no missing codes. The device includes an on‑board reference, low‑power operation (18 mA max), and is supplied in a 16‑lead SOIC package.
The document lists detailed electrical specifications, timing parameters, insulation and safety ratings (5000 Vrms for 1 minute per UL 1577), regulatory approvals, and pin descriptions. It also includes application notes for AC motor controls, data‑acquisition systems, and A/D plus opto‑isolator replacements.
