 The ADE9153A1 is a highly accurate, single-phase, energy metering IC with autocalibration. The mSure® autocalibration feature allows a meter to automatically calibrate the current and voltage channels without using an accurate source or an accurate reference meter when a shunt resistor is used as a current sensor. Class 1 and Class 2 meters are supported by mSureautocalibration. The ADE9153A incorporates three high performance analog- to-digital converters (ADCs), providing an 88 dB signal-to-noise ratio (SNR). The ADE9153A offers an advanced metrology feature set of measurements like line voltage and current, active energy, fundamental reactive energy, and apparent energy calculations, and current and voltage rms calculations. ADE9153A includes power quality measurements such as zero crossing detection, line period calculation, angle measurement, dip and swell, peak and overcurrent detection, and power factor measur...
