This product is a high-precision, 50/60Hz IEC 62053-21 standard-compliant three-phase energy metering IC with high accuracy, multiple wiring options, multiple output functions, and built-in driver circuits and high anti-interference capabilities.
The ADE7762 is a high‑accuracy polyphase energy‑metering integrated circuit that supports 50 Hz/60 Hz IEC 62053‑21 measurements. It offers average active‑power outputs (F1, F2), a high‑frequency calibration output (CF), phase‑drop and sequence‑error detection, and direct drive capability for electromechanical counters or 2‑phase stepper motors. All signal processing is performed digitally, providing stability over wide temperature and environmental ranges.
The device is supplied in a 28‑lead SOIC package, operates from a single 5 V supply, and includes on‑chip reference, power‑supply monitoring, and ESD protection. Detailed pin functions, timing characteristics, and absolute maximum ratings are provided for designers integrating the IC into energy‑metering applications.
