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 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. Note that throughout this data sheet， multifunction pins， such as ZX/DREADY/CF2， are referred to either by the entire pin name or by a single function of the pin， for example， CF2， when only that function is relevant. The ADE9153A operates from a 3.3 V supply and is available in a 32-lead LFCSP package.
