MCP46XXDM-PTPLS

The MCP46XXDM-PTPLS is a PICtail Plus daughter board demonstrates the features and abilities of MCP45XX and MCP46XX digital potentiometers. This board is designed to exclusively use the MCP46X1 devices. The MCP45XX and MCP46XX are digital potentiometers with an I2C 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 easily operate with explorer 16 development board or PICkit serial analyser or other PICDEM demo board that includes a PICtail Plus female connector. The use of the explorer 16 board will require a tool to program the supplied firmware into the PIC24FJ128GA010 device. The use of any other PICDEM board will require the user to modify the supplied C source program appropriately. The use of the PICkit Serial analyser will require the PC GUI interface program to control the command and data sent to the MCP42XX devices serial port.

• PICkit serial analyser interface
• PICtail plus interface
• MAX4582L high voltage analog switch to allow HVC voltage to be selected as one of four voltages
• Jumpers to connect wiper pins (W0 and W1) to the PICDEM analog channels
• Jumpers to allow terminal A pins to be connected to the AVDD or VAx (0,1)pad
• Jumpers to allow terminal B pins to be connected to the VSS 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

Applications
