Product Overview

MCP42XXDM-PTPLS is an PICtail Plus Daughter Board used to demonstrate the operation of the MCP42XX digital potentiometers. The operation of the MCP41XX devices is similar to the MCP42XX devices. Therefore, this demo board can be used as a development platform for either device family. The MCP41XX and MCP42XX are digital potentiometers with an SPI interface. These devices have either 7bits or 8bits of resolution, single or dual offering, and are available as either volatile or Non-volatile memory options. This board is designed to be used in conjunction with either the PIC24 Explorer 16 Demo Board or the PICkit Serial Analyzer.
  • Each digital potentiometers Terminal A pin can be individually connected to either AVDD or VAx pad
  • Each digital potentiometers Terminal B pin can be individually connected to either AVSS or VBx pad
  • Can control the voltage on MCP4261’s CS pin to either VSS, 3.3V, 5.0V, or 9.0V via control signals
  • 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
