March 22, 2012 – Analog Devices ( www.analog.com ), a global leader in data converters for signal processing and high-performance semiconductors, today introduced a single-chip energy measurement analog front-end (AFE) capable of monitoring energy consumption and power quality for up to six electrical circuits. The ADE7816 energy measurement AFE is designed for data center power distribution units, energy monitoring and management systems, and multi-channel electric meters. The newly released AFE can measure one voltage and up to six current channels, providing highly accurate energy usage and power quality data for each circuit. Because the ADE7816 energy measurement AFE interoperates with standard microcontrollers, it offers superior processor flexibility compared to System-on-Chip (SoC) devices with fixed configurations and allows for the configuration of various peripheral options. Furthermore, multiple ADE7816 energy measurement AFEs can interface with a single application processor, making it a much more useful solution than SoC products in terms of scalability and cost-effectiveness. .

Key specifications of the ADE7816 energy measurement AFE
• Supports flexible system design by enabling interfacing with various user-selectable microcontroller configurations.
• Implement a scalable system design by using multiple ADE7816 AFEs with a single application MCU
• Implementation of a flexible system design supporting shunts, Rogowski coils, and current transformers
• Real-time access to raw waveform samples is possible through flexible interfaces such as I2C, SPI (Serial Port Interface), and HSDC (High-Speed Data Capture).
• Can replace 6 single-phase energy metering ICs, saving board space and costs
• ADI in-house field-verified ratings for active/reactive energy and instantaneous RMS voltage/current
• Utilizes built-in power quality information (overvoltage, overcurrent, peak, and degradation detection functions) to reduce development time.
• Provides industry-leading active and reactive energy error rates of less than 0.2% over a dynamic range of 3000:1, meeting the accuracy requirements of a Class 0.5 electric meter.
