ADE7816

Six Current, One voltage Channel Energy Metering IC
Manufactured by:

Product Details

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 a complete 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, such as overcurrent, overvoltage, peak, and sag detection, is accessible via the two external interrupt pins, IRQ0 and IRQ1.

The ADE7816 energy metering IC operates from a 3.3 V supply voltage and is available in a 40-lead LFCSP that is Pb free and RoHS compliant.
