ADE7878AACPZ

Energy Metering Overview

The ADE7878AACPZ-RL is a polyphase multifunction energy metering IC from Analog Devices, designed for high-accuracy power monitoring. It integrates six second-order sigma-delta ADCs and digital signal processing to measure active, reactive, and apparent energy in three-phase systems (Y or Delta). The device supports total and harmonic measurements with an input impedance of 400 kΩ and operates on a 2.8 V to 3.7 V supply. It features SPI communication and is housed in a 40-LFCSP-WQ package.

Energy Metering Feature Summary
