The ADE9153A is a highly accurate, single-phase, energy metering IC with autocalibration. ThemSure®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 bymSure autocalibration.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 measurements. Each input channel supports independent and flexible gain stages. Current Channel A is ideal for shunts, having a flexible gain stage and providing full-scale input ranges from 62.5 mV peak down to 26.04 mV peak. Current Channel B has gain stages of 1×, 2×, and 4× for use with current transformers (CTs). A high speed, 10 MHz, serial peripheral interface (SPI) port allows access to the ADE9153A registers.The ADE9153A operates from a 3.3 V supply and is available in a 32-lead LFCSP package.ApplicationsSingle-phase energy metersEnergy and power measurementStreet lightingSmart power distribution systemMachine health
