ADE7858AACPZ-RL

ADE7858A is a polyphase multifunction energy metering IC. It contains waveform sampling registers that allow access to all ADC outputs. It also incorporate power quality measurements, such as short duration low or high voltage detection, short duration high current variation, line voltage period measurement, and angles between phase voltages and currents. Two serial interfaces, serial peripheral interface (SPI) and I²C, can communicate with the devices. A dedicated high speed interface, the high speed data capture (HSDC) port, can be used in conjunction with I²C to provide access to the ADC outputs and real-time power information. This device have two interrupt request pins, IRQ0 and IRQ1, to indicate that an enabled interrupt event has occurred.
