1% error in active and reactive energy measurements over a dynamic range of 3000:1 Less than 0.
2% error in instantaneous IRMS measurement over a dynamic range of 1000:1 Provides apparent energy measurement and instantaneous power readings 1.
23 kHz bandwidth operation Flexible PGA gain stage (up to ×22) Includes internal integrators for use with Rogowski coil sensors SPI, I2C, or UART communication GENERAL DESCRIPTION The ADE7953 is a high accuracy electrical energy measurement IC intended for single phase applications.
It measures line voltage and current and calculates active, reactive, and apparent energy, as well as instantaneous rms voltage and current.
The device 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.
Two configurable low jitter pulse output pins provide outputs that are proportional to active, reactive, or apparent energy, as well as current and voltage rms.
A full range of power quality information such as overcurrent, overvoltage, pea...
