Energy Measurement 40Pin LFCSP EP T/R
Product Details
The ADE7868 is a high accuracy, 3-phase electrical energy measurement IC with serial interfaces and three flexible pulse outputs. The ADE7868 incorporates second-order Σ-Δ ADCs, a digital 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 ADE7868 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 ADE7868 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/reactive/apparent power or sum of current rms values.
The ADE7868 has waveform sample registers that allow access to all ADC outputs. The device also incorporates power quality measurements 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. Two serial interfaces can be used to communicate with the ADE7868: SPI or I2C while a dedicated high speed interface, HSDC High Speed Data Capture port, can be used in conjunction with I2C to provide access to the ADC outputs and real time power information. The ADE7868 has also two interrupt request pins, IRQ0 and IRQ1, to indicate that an enabled interrupt event has occurred. Three specially designed low power modes ensure the continuity of the energy accumulation when the ADE7868 is in tampering situation. The ADE7868 is available in 40-lead LFCSP lead free package.
