Six Current Channels, One Voltage Channel

Energy Metering IC

Data Sheet

ADE7816

voltage and current. The device incorporates seven sigma-delta

(Σ-Δ) ADCs with a high accuracy energy measurement core.

FEATURES

Measures active and reactive energy, sampled waveforms,

and current and voltage rms

6 current input channels and 1 voltage channel

<0.1% error in active and reactive energy over a dynamic

range of 1000:1

Supports current transformer and Rogowski coil sensors

Provides instantaneous current and voltage readings

Angle measurements on all 6 channels

2 kHz bandwidth operation

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

Reference: 1.2 V (drift 10 ppm/°C typical) with external

overdrive capability

Flexible I²C, SPI, and HSDC serial interfaces

GENERAL DESCRIPTION

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

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.
