    &lt;p&gt;The MCP3905A Energy Meter Reference Design (using the MCP3905A/06A device) 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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;The MCP3905A/06A Energy Meter Reference Design is a stand-alone, single-phase residential meter design for active -energy meter designs. For advanced microcontroller-based meter products, this design also serves as the design of the Analog Front-End (AFE). This design includes a low-cost DC power supply circuit and the necessary protection for IEC62053 EMC compliance.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Key Application:&lt;/strong&gt; Energy Meter Design&lt;/p&gt;

    &lt;p&gt;The MCP3905A Energy Meter Reference Design (using the MCP3905A/06A device) 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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;The MCP3905A/06A Energy Meter Reference Design is a stand-alone, single-phase residential meter design for active -energy meter designs. For advanced microcontroller-based meter products, this design also serves as the design of the Analog Front-End (AFE). This design includes a low-cost DC power supply circuit and the necessary protection for IEC62053 EMC compliance.&lt;/p&gt;
