Analog Devices Inc. ADE9153A Energy Metering ICs with Autocalibration

Developed using three high-performance analog-to-digital converters (ADCs), the ADE9153A ICs offer an 88dB signal-to-noise ratio (SNR) and an advanced metrology feature set of measurements. These measurements include line voltage and current, active energy, fundamental reactive energy, and apparent energy calculations, and current and voltage rms calculations. ADE9153A provides power quality measurements such as zero crossing detection, line period calculation, angle measurement, dip and swell, peak and overcurrent detection, and power factor measurements.

Each of ADE9153A'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 1×, 2×, and 4× for use with current transformers (CTs). A high-speed 10MHz serial peripheral interface (SPI) port allows access to the ADE9153A registers.
