 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. |
| The MCP42XX PICtail Plus Daughter Board is used to demonstrate the operation of the MCP42XX Digital Potentiometers. The operation of the MCP41XX devices is similar to the MCP42XX devices. |
| The MCP4xxx Digital Potentiometer Daughter Board allows the system designer to quickly evaluate the operation of Microchip Technology’s MCP42XXX and MCP402X Digital Potentiometers.
|
| The 14-Lead SOIC/TSSOP/DIP Evaluation Board allows the system designer to quickly evaluate the operation of Microchip Technology’s devices in either SOIC, DIP, or TSSOP packages. |
