7. In this step, you have to select the V
DD
voltage of the MCP3423 Evaluation
Board, then click the
Next
button.
Case 1: When you use V
DD
from the PICkit Serial Analyzer:
If you choose
PICkit Serial will power your device
and
5 Volts
as shown in
Figure 1-7, the MCP3423 Evaluation Board is powered by the 5V DC from the
PICkit Serial Analyzer through the JP1 jumper. In this case, make sure that the
JP1 jumper on the MCP3423 Evaluation Board is connected.
Case 2: When you use your own V
DD
:
You can also provide your own V
DD
voltage by applying a V
DD
voltage at VD1
test point. In this case, make sure that the JP1 jumper is disconnected.
Note:
The MCP3423 Evaluation Board has its own pull-up resistors.
