DESCRIPTIONThe ADE7754 is a high accuracy polyphase electrical energymeasurement IC with a serial interface and a pulse output. TheADE7754 incorporates second order - ADCs, referencecircuitry, temperature sensor, and all the signal processingrequired to perform active, apparent energy measurements, andrms calculation.The ADE7754 provides different solutions for measuring activeand apparent energy from the six analog inputs, thus enablingthe use of the ADE7754 in various power meter services such as3-phase/4-wire, 3-phase/3-wire, and 4-wire delta.In addition to rms calculation, active and apparent power infor-mation, the ADE7754 provides system calibration features foreach phase (i.e., channel offset correction, phase calibration,and gain calibration). The CF logic output provides instanta-neous active power information.The ADE7754 has a waveform sample register that enablesaccess to ADC outputs. The part also incorporates a detectioncircuit for short duration low or high voltage variat FEATURESHigh Accuracy, Supports IEC 687/61036Compatible with 3-Phase/3-Wire, 3-Phase/4-Wireand any Type of 3-Phase ServicesLess than 0.1% Error in Active Power Measurement over aDynamic Range of 1000 to 1Supplies Active Energy, Apparent Energy, Voltage RMS,Current RMS, and Sampled Waveform DataDigital Power, Phase, and Input Offset CalibrationOn-Chip Temperature Sensor ( 4 C Typical after Calibration)On-Chip User Programmable Thresholds for Line VoltageSAG and Overdrive DetectionsSPI Compatible Serial Interface with InterruptRequest Line (IRQ)Pulse Output with Programmable FrequencyProprietary ADCs and DSP Provide High Accuracy overLarge Variations in Environmental Conditions and TimeSingle 5 V SupplyGENERAL DESCRIPTIONThe ADE7754 is a high accuracy polyphase electrical energymeasurement IC with a serial interface and a pulse output.
