ADE7753ARS

Product Summary

The ADE7753ARS is an accurate active and apparent energy measurements IC with a serial interface and a pulse output. The ADE7753ARS 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. The ADE7753ARS has a positive only accumulation mode which gives the option to accumulate energy only when positive power is detected.The ADE7753ARS is available in 20-lead SSOP package.
