ADE7760 is a high-accuracy active energy measurement IC produced by Analog Devices. It supports the IEC 687/61036 standard and has a dynamic range of 500:1. The output frequency is F1 and F2, and the high-frequency output CF is used for calibration and provides instantaneous active power. In addition, it can monitor the phase current and neutral current to realize fault detection in 2-wire distribution systems.
The ADE7760 is a high‑accuracy, fault‑tolerant energy‑metering IC designed for 2‑wire distribution systems. It measures active energy with less than 0.1 % error over a wide dynamic range and includes on‑chip fault detection that monitors phase and neutral currents.
Key features include dual frequency outputs for average active power (F1, F2), a calibration output (CF) for instantaneous power, logic fault indicators (FAULT, REVP), and a single 5 V supply. The device provides extensive specifications such as 0.01 % output frequency variation, 6.25 % fault detection threshold, and a 450 kHz internal oscillator.

The ADE7760 operates from a single 5 V supply with a tolerance of ±5 %.
It provides two logic outputs, FAULT and REVP, which can be used to signal a potential mis‑wiring or fault condition.
The on‑chip oscillator runs at 450 kHz.
