ADI公司的ADE7816是精密的多路(六个电流通路,一个电压通路)电表集成电路,可以测量线路电压和电流,-delta (Σ-Δ) ADC和高精度能量测量内核,动态范围1000:%,支持电流变压器和Rogowski线圈传感器,工作带宽2kHz,,功能方框图, 测试电路图, 信号流程框图, 有功和无功功率信号流程框图,以及ADE7816评估板主要特性和电路图.
The ADE7816 is a highly accurate, multichannel metering device that is capable of measuring one voltage channel and up to six current channels. It measures line voltage and current and calculates active and reactive energy, as well as instantaneous rms
voltage and current. The device incorporates seven sigma-delta (Σ-Δ) ADCs with a high accuracy energy measurement core. The six current input channels allow multiple loads to be measured simultaneously. The voltage channel and the six current channels each have plete signal path allowing for a full range of measurements. Each input channel supports a flexible gain stage and is suitable for use with current transformers (CTs). Six on-chip digital integrators facilitate the use of the Rogowski coil sensors.
The ADE7816 provides access to on-chip meter registers via either the SPI or I2C interface. A dedicated high speed interface, the high speed data capture (HSDC) port, can be used in conjunction with I2C to provide access to real-time ADC output information. A full range of power quality information,
