Figure 2.6 Analog Output Voltage Setting
The internal D/A reference voltage can be set to –5V or –10V by JP3. The
possible configurations are specified as Figure 2.7. Note that the internal
reference voltage is used only when the JP4 is set to internal reference only.

Figure 2.7 Internal Reference Voltage Setting
Note: If the -10V D/A reference voltage is selected, the D/A output range is
0V~10V. On the other hand, if the -5V is selected, the D/A output
range is 0V~5V.
