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 and |
