2.1
INTRODUCTION
The MCP42XX PICtail Plus Daughter Board is used to demonstrate the operation of 
Digital Potentiometer. The operation of the MCP41XX devices is similar to the 
MCP42XX devices. Therefore, this demo board can be used as a development plat-
form for either device family.
This board is designed to be used in conjunction with either the PIC24 Explorer 16 
Demo Board or the PICkit™ Serial Analyzer. 
2.2
FEATURES
This board supports the following features
• Each digital potentiometers Terminal A pin can be individually connected to either 
AV
DD
 or the corresponding VAx pad
• Each digital potentiometers Terminal B pin can be individually connected to either 
AV
SS
 or the corresponding VBx pad
• Can control the voltage on the MCP4261’s CS pin to either V
SS
, 3.3V, 5.0V, or 
9.0V via control signals from the PICtail Plus interface (J3)
• Can Control the MCP4261 via the PICkit™ Serial Analyzer interface (J1)
• PIC24 can monitor the voltage levels of the MCP4261’s W0 and W1 pins
• Supplied with a “C” program that demonstrates normal and high voltage 
commands
• Demonstrates a split rail application, with digital logic at 3.3V and analog 
operation at 5.0V
