The ADE7880 is a high accuracy, 3-phase electrical energy measurement IC featuring an adaptive real time monitoring (ARTM) harmonic engine. ARTM is capable of monitoring three user selectable harmonics, in addition to the fundamental. ARTM automatically tracks fundamental frequency and provides real-time harmonic measurement updates. Harmonic analysis includes current rms, voltage rms, active, reactive, and apparent powers, power factor, harmonic distortion, and total harmonic distortion plus noise (THD + N) calculations. The ADE7880 incorporates seven second-order Σ-Δ ADCs, a digital integrator, reference circuitry, and all the signal processing required to perform total (fundamental and harmonic) active, fundamental active, fundamental reactive, and apparent energy measurement and rms calculations. The ADE7880 is suitable to measure active, reactive, and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires. This metering IC provides system calibration features for each phase: rms and energy offset correction, phase calibration, and gain calibration. The ADE7880 supports IEC 62053-21, IEC 62053-22, IEC 62053-23, EN 50470-1, EN 50470-3, ANSI C12.20, and IEC 61000-4-7 standards. The ADE7880 is pin compatible with the popular ADE7878, ADE7868, ADE7858, and ADE7854 3-phase energy metering ICs.
