MCP3905EV

The MCP3905EV is a MCP3905A evaluation board designed to test a variety of meter designs using the MCP3905A energy metering Integrated Circuit. The stand alone MCP3905A energy meter designs, as well as those using a PICmicro MCU Unit , are easily designed using this evaluation board as the prototype analog front end. The high voltage AC input line and load connections, including the necessary space for current shunt or current transformer evaluation, are all included. Jumpers with shunts and a reset switch are connected to the MCP3905A device to further facilitate device evaluation and meter design. multiple input channel configuration circuits are included for both differential and single ended signals. LEDs for evaluating the MCP3905A output visually are on board. A standard 14 pin PICtail daughter board header is included for a connection to a variety of PICmicro microcontroller demonstration boards, allowing for PIC16, PIC18 and dsPIC DSC development system meter designs.
