MCP3905RD-PM1: Single Phase Energy Meter

Summary

The MCP3905 Energy Meter Reference Design is a stand-alone low cost energy meter. It can act as either a stand alone energy meter, or as the analog front end design for LCD microcontroller based meters.

The MCP3905 design is specified with an energy measurement error of 0.1% typical across 1:500 dynamic range for high accurate energy meter designs. This reference design is compliant with EMC requirements per energy metering standards IEC62053 and legacy IEC61036, IEC1046 and IEC687.

Features:

Demonstration board is a ready to use single-chip low cost energy meter
Direct connection to line for energy meter, no transformers required
On-board power supply circuitry
Resistive network and Output LED for meter calibration
Resistor shorts for gain and frequency selection
