This document describes the ADE7759 active energy metering IC, which features high accuracy, on-chip digital integrator, and interface with current sensors with di/dt output.
The ADE7759 is an accurate active power and energy measurement IC with a serial interface and a pulse output. It incorporates two second-order Σ-∆ ADCs, a digital integrator for Channel 1, reference circuitry, a temperature sensor, and all signal processing required for active power and energy measurement. An on-chip digital integrator allows direct interface to di/dt current sensors such as a Rogowski coil, eliminating the need for an external analog integrator.
