ADE7854AACPZ-RL

Energy Metering Overview

The ADE7854AACPZ-RL is a polyphase multifunction energy metering IC from Analog Devices, designed for high-accuracy three-phase power measurement. It integrates second-order sigma-delta analog-to-digital converters (ADCs), digital integrators, and reference circuitry to perform total active and apparent energy measurements, including fundamental and harmonic components. The device supports RMS calculations and fundamental-only active and reactive energy measurements. It features a 24-bit resolution, six channels, and operates within a supply voltage range of 2.8 V to 3.7 V. The component is housed in a 40-LFCSP-WQ package and communicates via an SPI interface.
