Analog Devices metering IC for machine health, intelligent lighting and power distribution systems

The ADE9153 is a single-phase power metering automatic calibration IC mSure Automatic calibration feature allows meters to automatically calibrate current and voltage channels without using an accurate source or an accurate reference meter when shunt resistance is used as a current sensor. Levels 1 and 2 are automatically calibrated by mSure. The ADE9153 integrates three high-performance analog-to-digital converters (ADCs) to deliver an 88 dB signal-to-noise ratio (SNR).

The ADE9153 offers a suite of advanced measurement features such as line voltage and current, active energy, basic nonfunctional and apparent energy calculations, and current and voltage RMS calculations. The ADE9153 includes power quality measurements such as zero crossing detection, line period calculation, Angle measurement, dip and swell, peak and overcurrent detection, and power factor measurement.

Each input channel supports independent and flexible gain stages. Current Channel A is ideal for a shunt with a flexible gain stage that provides a full range of input from peak 62.5mV to peak 26.04mV. The gain stages of current channel B are 1 x, 2 x, and 4 x for current transformers. The high-speed 10 MHz Serial Peripheral Interface (SPI) port allows access to the ADE9153 register.
