MCP3909 DataSheet
http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gifEnergy Metering IC with SPI Interface and Active Power Pulse OutputThe MCP3909 is an energy measurement IC supporting the IEC 62053 international energy metering specification. The output of the device includes a frequency proportional to the average active (real) power at the inputs as well as a simultaneous serial SPI interface to access the ADC channels and multiplier output data. The MCP3909 incorporates two 16-bit delta-sigma ADCs with a progammable gain up to 16, which enable small shunt meter designs for measuring a wide range of Ib and Imax currents. The output waveform data is available at up to 14 kHz with 16-bit ADC output and 20-bit multiplier output data. The integrated on-chip voltage reference has an ultra-low temperature drift of 15 ppm per degree C.
