The ADE7763 is a single-phase active and apparent energy metering IC from Analog Devices that supports IEC 61036/60687, IEC62053-21, and IEC62053-22 standards. It features high accuracy, low power consumption, an on-chip digital integrator, A/D converter, SPI interface, etc.
The ADE7763 is a single‑phase active and apparent energy‑metering IC that integrates high‑accuracy ADCs, a digital integrator, on‑chip reference, and temperature sensor to measure active and apparent power, RMS voltage/current, and waveform sampling. It supports IEC energy‑measurement standards and offers a SPI‑compatible serial interface, pulse output, and programmable thresholds.
The datasheet includes detailed specifications, absolute maximum ratings, pin configuration, timing characteristics, and descriptions of key functions such as zero‑crossing detection, line‑voltage sag detection, interrupt handling, and power‑supply rejection. It also provides calibration procedures, typical performance graphs, and revision history for designers integrating the part into metering solutions.
