GETTING STARTED
The MCP4XXX Digital Potentiometer Daughter Board is a board that allows the Digital
Potentiometer circuit to be configured in many forms for evaluation of the device. The
Resistor Network Circuit is shown in Figure 2-1 and shows the possible configurations
that the demo board supports.
The passive components use the surface-mount 805 package layout. Figure 2-2 shows
the board circuit.
This demo board supports the following Microchip Digital Potentiometers devices:
• MCP42XXX
• MCP4021
• MCP4011
