The ADE7756 is a high-precision active energy metering IC produced by Analog Devices, supporting IEC687/1036 standard, with a dynamic range of 1000:1 and an error of less than 0.1%. It has the function of line voltage SAG detection and PSU supervision, and an on-chip temperature sensor. It can communicate data via SPI-compatible serial interface
The ADE7756 is a high‑accuracy electrical power measurement IC that provides active energy, waveform sampling and a programmable pulse output. It includes two sigma‑delta ADCs, on‑chip reference, temperature sensor and calibration features such as offset, phase and power correction. The device also offers line‑voltage sag detection, zero‑crossing and interrupt outputs for system monitoring.
The IC is supplied in 20‑lead DIP and 20‑lead SSOP packages and uses a 4‑wire SPI‑compatible serial interface. Detailed specifications cover supply voltage, input ranges, reference voltage, temperature coefficient, power‑supply rejection and absolute maximum ratings.
