ADE7868AACPZ-RL

Energy Metering Overview

The ADE7868AACPZ-RL is a polyphase multifunction energy metering IC from Analog Devices, designed for high-accuracy power measurement in three-phase systems. It integrates seven second-order sigma-delta analog-to-digital converters (ADCs) with a resolution of 24 bits and a sampling rate of 8 kS/s. The device operates on a single supply voltage ranging from 2.8 V to 3.7 V and supports six channels for comprehensive phase monitoring. Communication is facilitated via an SPI interface, while the component is housed in a 40-lead LFCSP package suitable for surface mount applications.
