    • Evaluation Board for MCP3905A Energy Meter Design


    The MCP3905A Evaluation board is designed (using the MCP3905A device) to test out a variety of energy meter designs. On the input side high voltage line and load AC-plug headers are included, along with mounting holes for shunts, current transformers, and screw-type connections for wiring.

    The MCP3905A/06A Evaluation Board provides easy evaluation of the MCP3905A energy-metering IC to metering customers. High-voltage AC input line and load connections, including the necessary space for current shunt or Current Transformer (CT) evaluation, are all included. Jumpers with shunts and a reset switch are connected to the MCP3905A/06A 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/06A output visually are on-board. A standard 14-pin PICtail™ daughter board header is included for a connection to a variety of Microchip PICmicro® microcontroller demonstration (demo) boards, allowing for PIC16, PIC18 and dsPIC® DSC development system meter designs. This connection can also be isolated using an on-board, optical-isolation IC.

    Key Application: Energy Meter Designs
