Description

General part information

MCP3905A Series

The MCP3905L 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 higher frequency output proportional to the instantaneous power for meter calibration. The MCP3905L 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 integrated on-chip voltage reference has ultra-low temperature drift of 15 ppm per degree C. Also on-chip is a fixed-function DSP for active (real) power calculation. The MCP3905L offers reduced pulse width of calibration output frequency and mechanical counter drive for low power meter designs.
