ADE7854AACPZ are high accuracy, 3-phase electrical energy measurement ICs with serial interfaces and three flexible pulse outputs. The devices incorporate second-order Σ-Δ analog-to-digital converters (ADCs), a digital integrator, reference circuitry, and all signal processing required to perform total (fundamental and harmonic) active, reactive (ADE7858A, ADE7868A, and ADE7878A), and apparent energy measurement and rms calculations. 

ADE7854AACPZ can also perform fundamental-only active and reactive energy measurement and rms calculations. A fixed function digital signal processor (DSP) executes the signal processing. The DSP program is stored in the internal ROM memory.

ADE7854AACPZ can measure active, reactive, and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires. Aside from regular rms measurements, which are updated every 8 kHz, these devices measure low ripple rms values, which are averaged internally and updated every 1.024 sec. The devices provide system calibration features for each phase, that is, rms offset correction, phase calibration, and gain calibration.
