GENERAL DESCRIPTION
The ADE7753 is an accurate active and apparent energy measurements IC with a serial interface and a pulse output. The ADE7753 incorporates two second order sigma delta ADCs, a digital integrator (on CH1), reference circuitry, temperature sensor, and all the signal processing required to perform RMS calculation on the voltage and current, active, reactive, and apparent energy measurement.
