MCP3905 Datasheet (Microchip Technology) - (MCP3905 / MCP3906) Energy-Metering ICs

MCP3905, (MCP3905 / MCP3906) Energy-Metering ICs

The MCP3905/06 devices are energy-metering ICs designed to support the IEC 62053 International Metering Standard Specification.

They supply a frequency output proportional to the average active (real) power, as well as a higher-frequency output proportional to the instantaneous power for meter calib
