This data sheet describes the features of the ADE7816 energy metering IC, including measuring current, voltage, power, phase angle, etc., as well as I2C, SPI, HSDC interfaces
The Analog Devices ADE7816 is a highly accurate, multichannel metering device designed to measure one voltage channel and up to six current channels. It calculates active and reactive energy, as well as instantaneous rms voltage and current, utilizing seven sigma-delta ADCs with a high accuracy energy measurement core.
The device supports flexible gain stages suitable for current transformers (CTs) and Rogowski coil sensors via on-chip digital integrators. It provides access to meter registers through SPI or I2C interfaces and includes a dedicated High Speed Data Capture (HSDC) port for real-time ADC output information.
| Active Energy Measurement Error | < 0.1% |
