ADE7759ARSZRL

GENERAL DESCRIPTION

The ADE7759 is an accurate active power and energy measurement IC with a serial interface and a pulse output. The ADE7759 incorporates two second-order Σ-∆ ADCs, a digital integrator (on CH1), reference circuitry, temperature sensor, and all the signal processing required to perform active power and energy measurement.
