2.4.6 Evaluating the MCP4361 Device (A Digital Potentiometer)
The MCP4361 is a Digital Potentiometer that is in a 20-lead TSSOP package with an
SPI serial interface. This allows the device to be communicated to by the PICkit Serial
Analyzer. For this to occur, the PICkit Serial Analyzer signals must be connected to the
correct MCP4018 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.
