This document describes the features and characteristics of the ADE7763 single-phase active and apparent energy metering integrated circuit, including high accuracy, support for multiple international standards, direct interface to current sensors and shunts, support for energy accumulation mode, and digital calibration.
The ADE7763 integrates proprietary ADCs, a digital integrator, and on‑chip reference to provide precise active and apparent energy measurements, line‑voltage period measurement, and RMS calculations for voltage and current channels. It supports direct connection to di/dt current sensors such as Rogowski coils and includes programmable thresholds for voltage sag and surge detection.
The device operates from a single 5 V supply, offers a pulse output proportional to active power, and provides multiple interrupt and status signals. It is supplied in a 20‑lead SSOP package and includes extensive calibration features for offset, phase, and power.

AVDD may be as low as –0.3 V and as high as +7 V relative to AGND.
The ZX output toggles logic high and low at the zero‑crossing of the differential signal on Channel 2.
The analog input impedance is at least 390 kΩ (dc).
The device operates from –40 °C to +85 °C in industrial environments.
