The ADE7858 is a high accuracy, 3-phase electrical energymeasurement IC with serial interfaces and three flexible pulseoutputs. The ADE7858 incorporates second-order Σ-Δ ADCs, adigital integrator, reference circuitry, and all the signal processing required to perform total (fundamental and harmonic) active, reactive and apparent energy measurement, and rms calculations. A fixed function digital signal processor (DSP) executes this signal processing.
The ADE7858 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 ADE7858 provides system calibration features for each phase, that is, rms offset correction, phase calibration, and gain calibration. The CF1, CF2 and CF3 logic outputs provide a widechoice of power information: total active/reactive/apparentpower or sum of current rms values.
The ADE7858 has waveform sample registers that allow accessto all ADC outputs. The device also incorporates power qualitymeasurements such as short duration low or high voltagedetections, short duration high current variations, line voltageperiod measurement and angles between phase voltages andcurrents. Two serial interfaces can be used to communicate withthe ADE7858: SPI or I2C while a dedicated high speed interface, HSDC (High Speed Data Capture) port, can be used inconjunction with I2C to provide access to the ADC outputs and real time power information. The ADE7858 has also twointerrupt request pins, IRQ0 and IRQ1, to indicate that anenabled interrupt event has occurred.
The ADE7858 is available in 40-lead LFCSP lead free package.
