MCP3906AT-I/SS [Microchip]

The MCP3906A 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 MCP3906A features dynamic range of 1000:1 and incorporates two 16-bit delta-sigma ADCs with a programmable gain up to 32. The integrated on-chip voltage reference has ultra-low temperature drift of 15 ppm/°C.
