ADE7759 Single-Phase Metering IC with di/dt Input (Serial-Port Interface).

The ADE7759 is available in 20-lead SSOP package, and it is pin-to-pin compatible with the ADE7753 and ADE7756. NOTE: If your application requires the measurement of rms voltage and current, the ADE7763 is recommended.

The ADE7759 is an accurate active power and energy measurement IC with a serial interface and a pulse output. The ADE7759 incorporates two second-order sigma-delta ADCs, a digital integrator (on CH1), reference circuitry, temperature sensor and all the signal processing required to perform active power and energy measurement.

An on-chip digital integrator provides direct interface to current sensors such as Rogowski coil, which have di/dt output. The digital integrator eliminates the need for external analog integrator, and this solution provides excellent long-term stability and precise phase matching between the current and voltage channels. The integrator can be switched on and off based on the current sensor selected.
