The ADE7763ARSZ is a single-phase active and apparent energy Metering IC features proprietary ADCs and fixed function DSP for high accuracy over large variations in environmental conditions and time. The ADE7763 incorporates two second-order, 16-bit Σ-Δ ADCs, a digital integrator (on Ch1), reference circuitry, a temperature sensor and all the signal processing required to perform active and apparent energy measurements, line-voltage period measurements, RMS calculation on the voltage and current channels. The selectable on-chip digital integrator provides direct interface to di/dt current sensors such as Rogowski coils, eliminating the need for an external analog integrator and resulting in excellent long-term stability and precise phase matching between the current and the voltage channels. The ADE7763 provides a serial interface to read data and a pulse output frequency (CF) that is proportional to the active power.
