Energy Metering IC or Module: ADE7768 (MOD5)

Quick Overview

The ADE7768 offers a cost-efficient solution for developing accurate and reliable energy metering systems. It’s particularly suitable for meter designs that require a reduced part count and favor an internal clocking mechanism. Its direct interfacing with a shunt resistor makes it a versatile component for a wide range of metering applications.

How It Works

The ADE7768 measures energy consumption by monitoring the voltage drop across a shunt resistor, which corresponds to the current passing through it. The integrated oscillator provides a stable clock signal for the chip, facilitating accurate energy readings. It converts analog signals from the resistor into digital data that can be processed and communicated to other parts of the metering system.
