Kit Overview

The Analog Devices ADE7816 evaluation kit (EVAL-ADE7816EBZEVAL-ADE7816EBZ) includes an evaluation board that allows the performance of the ADE7816ADE7816 6-channel energy measurement IC to be evaluated. The ADE7816 evaluation kit includes evaluation software, written in LabVIEW®, that provides access to the registers of the ADE7816 using a PC interface. This document provides information to assist the user in evaluating the ADE7816.

The ADE7816 evaluation kitADE7816 evaluation kit includes an evaluation board that is used to evaluate the silicon. The board includes the ADE7816ADE7816 energy measurement IC, associated filtering, and isolation to allow high voltage inputs to be applied. It also includes an NXP Semiconductors LPC2368FBD100LPC2368FBD100 microcontroller that handles all communication from the PC to the ADE7816.

The ADE7816ADE7816 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 ADE7816ADE7816 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.

Key Applications: Used in a variety of metering applications, including smart electricity meters, power distribution units, and in-home energy monitors.

ADE7816 Evaluation Software

The evaluation software is available in the ADE7816 Evaluation Board Software.zip file. The software can be run even if a licensed copy of LabVIEW is not available.

If the ADE7816 evaluation software is being used on the PC for the first time, an installer must be run. This installer is available in the Installer folder. To run the installer, double-click on the setup.exe file in the Installer folder. Follow the prompts to install the LabVIEW 2010 run-time engine. The ADE7816 evaluation software allows access to all registers and features of the ADE7816 using SPI, I2C, and HSDC communi-cation. The software also provide different functions for evaluating the performance of the ADE7816, such as active/reactive energy, RMS reading, waveform sampling, read/write registers, reset ADE7816, etc.
