ADE7753* 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.
An on-chip digital integrator provides direct interface to di/dt current sensors such as Rogowski coils. The digital integrator eliminates the need for external analog integrator, and this solution provides excellent long-term stability andprecise phase matching between the current and voltage channels. The integrator can be switched on and off based on the current sensor selected. The ADE7753 contains an Active Energy register. It is capable of holding more than 200 seconds of accumulated power at full load. Data is read from the ADE7753 via the serial interface. The ADE7753 also provides a pulse output (CF) with output frequency is proportional to the active power. In addition to rms calculation and active and apparent power information, the ADE7753 also accumulates the signed reactive energy. The ADE7753 also provides various system calibration features, i.e., channel offset correction, phase calibration and power calibration. The part also incorporates a detection circuit for short duration low or high voltage variations.
