MCP3909屬于開發(fā)板套件編程器的評估板-模數(shù)轉(zhuǎn)換器（ADC）。由美國微芯科技公司制造生產(chǎn)的MCP3909評估板 - 模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器 (ADC) 評估板是預(yù)裝有元器件的電路板，用于提供特定 ADC 或器件工作實例。特定板上的 A/D 轉(zhuǎn)換器數(shù)量從 3 到 32 不等，每秒采樣率從 2.5 kHz 到 26 GHz 不等，輸入電壓范圍從 0 到 8 Vp-p。

描述 Description

The MCP3909 device is an energy-metering IC designed to support the IEC 62053 international metering standard specification. It supplies a frequency output proportional to the average active real power, with simultaneous serial access to ADC channels and multiplier output data. This output waveform data is available at up to 14 kHz with 16-bit ADC output and 20-bit multiplier output words. The 16-bit, delta-sigma ADCs allow for a wide range of IB and IMAX currents and/or small shunt (
