The ADE7854 is a high accuracy, 3-phase electrical energymeasurement IC with serial interfaces and three flexible pulse outputs. The ADE7854 incorporates second-order, sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), a digital integrator, reference circuitry, and all the signal processing required to perform total active and apparent energy measurement and rms calculations. A fixed function digital signal processor (DSP) executes this signal processing.
The ADE7854 is suitable for measuring active and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires. The ADE7854 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 wide choice of power information: total active power, total apparent power, or the sum of the current rms values.
The ADE7854 includes waveform sample registers that allow accessto all ADC outputs. The device also incorporates power qualitymeasurements, such as short duration low or high voltage detections,short duration high current variations, line voltage period measurement, and angles between phase voltages and currents. The SPI and I2C serial interfaces can be used to communicate withthe ADE7854. A dedicated high speed interface, the high speeddata capture (HSDC) port, can be used in conjunction with I2C to provide access to the ADC outputs and real-time power information. The ADE7854 has also two interrupt request pins, IRQ0 and IRQ1, to indicate that an enabled interrupt event has occurred.
The ADE7854 is available in a 40-lead LFCSP RoHS-compliantpackage.
This designates products ADI does not recommend broadly for new designs.
