ADE7953ACPZ - ADI Function Overview

The ADE7953ACPZ is a Single-phase Multifunction Metering IC with neutral current measurement. It measures line voltage and current, calculates active, reactive and apparent energy, as well as instantaneous rms voltage and current. It incorporates three Σ-Δ ADCs with a high accuracy energy measurement core. The second input channel simultaneously measures neutral current and enables tamper detection and neutral current billing. The additional channel incorporates a complete signal path that allows a full range of measurements. Each input channel supports independent and flexible gain stages, making the device suitable for use with a variety of current sensors such as current transformers (CTs) and low value shunt resistors. Two on-chip integrators facilitate the use of Rogowski coil sensors. The ADE7953 provides access to on-chip meter registers via a variety of communication interfaces including SPI, I²C and UART.
