Analog Devices ADE78xx Series Polyphase Multifunction Energy Metering ICs Datasheet

The ADE7878, ADE7868, ADE7858, and ADE7854 are high accuracy, 3-phase electrical energy measurement ICs with serial interfaces and flexible pulse outputs. They incorporate six or seven second-order S-Δ ADCs, a digital integrator, reference circuitry, and all the signal processing required to perform total (fundamental and harmonic) active, reactive, and apparent energy measurement, fundamental only active and reactive energy measurement, and rms calculations.

These metering ICs are 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. They provide system calibration features for each phase: rms offset correction, phase calibration, and gain calibration. The CF1, CF2, and CF3 logic outputs provide a wide choice of power information: total/fundamental active/reactive power, total apparent power, or sum of current rms values.
