AFE IC from ADI measure one voltage and up to six current channels

Analog Devices, Inc. has introduced a single-chip energy measurement AFE (analog front end) that monitors the energy consumption and power quality of 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 electricity meters. Able to measure one voltage and up to six current channels. Since it interfaces to standard microcontrollers, the ADE7816 energy measurement AFE is specifically suited for applications that require more processor flexibility and peripheral options than is offered by fixed-configuration SOC (system-on-chip) devices. Multiple ADE7816 energy measurement AFEs can interface with a single application processor.
Other notable features include:
Flexible system design supports shunts, Rogowski coils and current transformers
Flexible I2C, SPI (serial port interface) and HSDC (high-speed data capture) provide access to real-time raw waveform samples
instantaneous rms voltage and currents
Provides less than 0.2 percent error in active and reactive energy over a dynamic range of 3000:1 and meets accuracy requirements of Class 0.5 revenue-grade electricity meters
