MCP402X Non-Volatile Digital Potentiometer Evaluation Board
MCP402X Non-Volatile Digital Potentiometer Evaluation Board ( MCP402XEV )

The MCP402xEV is a low cost evaluation board that quickly enables the user to exercise all of the features of the MCP402X Non-Volatile Digital Potentiometer. This kit includes 2 PCBs, one populated & one unpopulated. The populated PCB has an MCP4021-103E/SN digital pot configured as a “windowed” potentiometer using a 2.5kΩ pull-up and a 2.5kΩ pull-down resistor. The PCB supports...

MCP42XX Evaluation Board
MCP42XX Evaluation Board ( MCP42XXEV )

The MCP42XX Evaluation Board allows the system designer to quickly evaluate the operation of Microchip Technology’s MCP4261 Digital Potentiometer device. The board uses the TSSOP20EV Generic PCB and has been populated for the MCP4261. The 6-pin header (PICkit Serial) has been jumpered to the MCP4261’s appropriate pins. This allows the PICkit Serial to communicate with the device....
