This document introduces the function characteristics of ADE7759 active energy metering IC
The ADE7759 is an active‑energy metering IC with a serial SPI interface, on‑chip digital integrator, temperature sensor, and programmable thresholds for line‑voltage sag detection. It supports direct connection to di/dt current sensors such as Rogowski coils and provides pulse‑frequency output proportional to active power.
The document includes functional block diagrams, detailed pin descriptions, timing characteristics, absolute maximum ratings, and extensive electrical specifications such as supply voltage, input ranges, reference accuracy, and power‑supply rejection. It also covers calibration procedures, zero‑crossing detection, and interrupt handling for integration into measurement systems.
