ADE7880ACPZ

The ADE7880ACPZ is a Polyphase Multifunction Energy Metering IC with harmonic monitoring. It incorporates second-order sigma-delta (?-Δ) analogue-to-digital converters (ADCs), a digital integrator, reference circuitry and all of the signal processing required to perform the total (fundamental and harmonic) active and apparent energy measurements, rms calculations as well as fundamental-only active and reactive energy measurements. In addition, the ADE7880 computes the rms of harmonics on the phase and neutral currents and on the phase voltages, together with the active, reactive and apparent powers and the power factor and harmonic distortion on each harmonic for all phases. Total harmonic distortion (THD) is computed for all currents and voltages. A fixed function digital signal processor (DSP) executes this signal processing. The DSP program is stored in the internal ROM memory.
