Energy metering ICs features automatic calibration

19-07-2018 | Analog Devices | Semiconductors

Analog Devices ADE9153A Energy Metering ICs are highly accurate, single-phase energy metering ICs with mSure autocalibration. The mSure autocalibration feature allows a meter to automatically calibrate current and voltage channels without other calibrated sources or reference meters when a shunt resistor is used as a current sensor. The device's mSure autocalibration supports Class 1 and Class 2 meters.

Developed using three high-performance ADCs, the ICs offer an 88dB SNR and an advanced metrology feature set of measurements. These measurements comprise line voltage and current, fundamental reactive energy, active energy, and apparent energy calculations, and current and voltage rms calculations. The device offers power quality measurements such as zero crossing detection, angle measurement, dip and swell, line period calculation, peak and overcurrent detection, and power factor measurements.

Each of device's input channels supports flexible and independent gain stages. The Current Channel A is ideal for shunts, having a flexible gain stage and providing full-scale input ranges from 62.5mV peak down to 26.04mV peak. The Current Channel B has gain stages of 1x, 2x, and 4x for use with CTs. A high-speed 10MHz SPI port provides access to the device registers.
