INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP46XX PICtail™ Plus Daughter Board is used to demonstrate the operation of
digital potentiometers. The operation of the MCP45XX devices is similar to the
MCP46XX devices. Therefore, the MCP46XX PICtail™ Plus Daughter Board can be
used as a development platform for either device family.
The MCP46XX PICtail™ Plus Daughter Board is designed to be used in conjunction
with either the Explorer 16 Development Board or the PICkit™ Serial Analyzer.
The MCP46XX PICtail™ Plus Daughter Board supports the following features:
• Each digital potentiometer’s Terminal A pin can be individually connected to either
• Each digital potentiometer’s Terminal B pin can be individually connected to either
• It can control the voltage on the MCP4661’s HVC/A0 pin to either V
• It can control the MCP4661 via the PICkit™ Serial Analyzer interface (J2)
• PIC24 can monitor the voltage levels of the MCP4661’s W0 and W1 pins
• It is supplied with a “C” program that demonstrates normal and high voltage
• It demonstrates a split rail application, with digital logic at 3.3V and analog
