The ADE7953 is a high accuracy single phase electrical energy measurement IC that measures line voltage and current and calculates active power, reactive power, apparent power and energy.
The ADE7953 is a high‑accuracy single‑phase metering IC that measures active, reactive, and apparent energy as well as instantaneous voltage and current RMS. It includes a second current input for neutral current measurement and supports a variety of current sensors such as current transformers and Rogowski coils.
The document provides a functional block diagram, detailed specifications, timing characteristics for SPI and PC interfaces, pin configurations, calibration procedures, and interrupt descriptions. An ordering guide lists the available package options and evaluation board.
