Hot-selling and scarce ADE7758ARW Poly Phase Multifunction Energy Metering IC SOP28 spot stock

Product Descriptions

The ADE7758¹  is a high accuracy 3-phase electrical energymeasurement IC with a serial interface and two pulse outputs .The ADE7758 incorporates second-order ∑-∆ ADCs, a digitalintegrator, reference circuitry, temperature sensor, and all thesignal processing required to perform active, reactive, andapparent energy measurement and rms calculations .

The ADE7758 is suitable to measure active, reactive, andapparent energy in various 3-phase configurations, such asWYE or DELTA services, both with three or four wires . TheADE7758 provides system calibration features for each phase,i .e., rms offset correction, phase calibration, and powercalibration . The APCF logic output gives active powerinformation, and the VARCF logic output providesinstantaneous reactive or apparent power information .
