The ADE77581
is a high accuracy, 3-phase electrical energy
measurement IC with a serial interface and two pulse outputs.
The ADE7758 incorporates second-order Σ-Δ ADCs, a digital
integrator, reference circuitry, a temperature sensor, and all the
signal processing required to perform active, reactive, and
apparent energy measurement and rms calculations.
The ADE7758 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. The
ADE7758 provides system calibration features for each phase,
that is, rms offset correction, phase calibration, and power
calibration. The APCF logic output gives active power
information, and the VARCF logic output provides instantaneous
reactive or apparent power information (continued on Page 4).
