ADI公司的ADE9153A是帶mSure?自動校準(zhǔn)的高度準(zhǔn)確單相電能計量集成電路，集成了三個高性能模數(shù)轉(zhuǎn)換器（ADC），信噪比（SNR）88dB，支持有功能源標(biāo)準(zhǔn)IEC 62053-21，IEC 62053-22， EN50470-3， OIML R46和ANSI C12.20;支持無功能源標(biāo)準(zhǔn)IEC 62053-23 和IEC 62053-24，器件工作電壓3.3V，主要用在單相電表，能量和功率測量，街道照明，智能電源分布系統(tǒng)和機器健康。本文介紹了ADE9153A1主要特性，典型應(yīng)用電路和測試電路以及評估板EV-ADE9153ASHIELDZ主要特性和電路圖。

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.
