MCP46XX Evaluation Board
MCP46XX Evaluation Board ( MCP46XXEV )

The MCP46XX Evaluation Board allows the system designer to quickly evaluate the operation of Microchip Technology’s MCP4661 Digital Potentiometer device. The board uses the TSSOP20EV Generic PCB and has been populated for the MCP4661. The 6-pin header (PICkit Serial) has been jumpered to the MCP4661’s appropriate pins. This allows the PICkit Serial to communicate with the device....
