Evaluating the MCP41X2 Device (A Digital Potentiometer with
SPI interface)
SPI interface)
The MCP41X2 is a Digital Potentiometer that is in a 8-lead DIP package with an SPI
serial interface. This allows the device to be communicated to (Read and Write) by the
PICkit Serial Analyzer. For this to occur, the PICkit Serial Analyzer signals must be
connected to the correct MCP41X2 signals. These connections are shown in
Figure 2-7.
Other Digital Potentiometers that are supported by this evaluation board are shown in
Table 2-4.
