Overview

The ADE7978, the ADE7933/ADE7932, and ADE7923ARWZ-RL form achipset dedicated to measuring 3-phase electrical energy usingshunts as current sensors.The ADE7933/ADE7932 are isolated, 3-channel sigma-deltaanalog-to-digital converters (Σ-Δ ADCs) for polyphase energymetering applications that use shunt current sensors.

The ADE7978 incorporates power quality measurements, suchas short duration low or high voltage detection, short durationhigh current variations, line voltage period measurement, andangles between phase voltages and currents. Two serial interfaces,SPI and I2C, can be used to communicate with the ADE7978.A dedicated high speed interface—the high speed data capture(HSDC) port—can be used in conjunction with I2C to provideaccess to the ADC outputs and real-time power information.The ADE7978 also has two interrupt request pins, IRQ0 andIRQ1, to indicate that an enabled interrupt event has occurred.The ADE7978 is available in a 28-lead, Pb-free LFCSP package.
