New IC from Analog Devices

Analog Devices has introduced the ADE7754 – the electricity industry’s first digitally calibrated multi-function three-phase energy metering IC. It will allow meter manufacturers to have a single chip solution to meet the demands of the high-end electricity metering market. The ADE7754 will provide more information about three-phase connections by supplying active energy, apparent energy, voltage rms, current rms and waveform samples data.

An extension of the ADE product family, the ADE7754 includes digital power, phase and offset calibration registers for all three phases. It features excellent accuracy, with less than 0.1 % linearity error over a dynamic range of 1000 to 1, and it operates on a single 5V power supply. It is compatible with 3- and 4-wire distribution systems and can be used in three-phase C&I meters or submeters and industrial control applications.
