MCP3909-I/SS屬于集成電路（IC）的電能計量。由微芯科技股份有限公司制造生產(chǎn)的MCP3909-I/SS電能計量能量計量集成電路可用于單相、雙相和三相電力線系統(tǒng)中的高精度電能測量。這些器件可以測量線路電壓和電流，并且可以計算有功、無功和視在電能，以及瞬時均方根電壓和電流。

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 (
