ADE7753ARSZRL

Product Summary

The ADE7753ARSZRL is a Single-Phase Multifunction Metering IC with di/dt Sensor Interface. The ADE7753ARSZRL features proprietary ADCs and DSP for high accuracy over large variations in environmental conditions and time. The ADE7753ARSZRL incorporates two second-order 16-bit -ADCs, a digital integrator (on CH1), reference circuitry, temperature sensor, and all the signal processing required to perform active, reactive, and apparent energy measurements, line-voltage period measurement, and rms calculation on the voltage and current. The ADE7753ARSZRL 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 voltage channels.
