ADE7816

• Product Introduction

ADE7816 Six current channels, one voltage channel energy metering IC

ADE7816 is a high-precision, multi-channel metering device that measures one voltage channel and up to six current channels. It is capable of measuring line voltage and current, and calculating active and reactive power, as well as instantaneous voltage and current RMS. The device has seven sigma-delta ADCs and a high-precision energy metering core. Six current input channels allow for simultaneous measurement of multiple loads. Both the voltage channel and the six current channels integrate a complete signal path, allowing a wide range of measurements to be performed. Each input channel supports flexible gain stages and is suitable for use with current transformers (CTs). Six in-chip digital integrators facilitate the use of Roche coil sensors.

ADE7816 can access the on-chip metering registers via SPI or I2C interfaces. A dedicated high-speed data acquisition (HSDC) port can be used with I2C to access real-time ADC output information. Two external interrupt pins, IRQ0 and IRQ1, provide comprehensive power quality information such as overcurrent, overvoltage, peak, and dip detection.

The ADE7816 energy metering IC operates from a 3.3 V supply and is available in a 40-pin LFCSP package, which is lead-free and RoHS compliant.
