Summary Description:

The MCP46XX PICtail™ Plus Daughter Board demonstrates the features and abilities of Microchip’s MCP45XX and MCP46XX Digital Potentiometers. This board is designed to exclusively use the MCP46X1 devices. The MCP4661 uses an I²C™ interface and can be controlled via the PICkit Serial Analyzer interface or via the PICtail™ Plus interface.

Features:

• PICkit Serial Analyzer Interface
• PICtail Plus Interface
• MAX4582L High Voltage analog switch to allow HVC voltage to be selected as one of four voltages
  (V_SS, 3.3V, 5.0V, or 9.0V) - High Voltage command support
• Jumpers to connect Wiper pins (W0 and W1) to the PICDEM Analog Channels
• Jumper to allow AV_DD to be driven by external power supply while connected to the PICDEM board or the PICkit Serial Analyzer
• Jumpers to allow Terminal A pins to be connected to the AV_DD or VAx (0,1)pad
• Jumpers to allow Terminal B pins to be connected to the V_SS or VBx (0,1) pad
• Connection point for easy connection to the Resistor Network Terminal pins
• PIC24 C program using standard Microchip “C” I²C™ Libraries
