Figure 2.4 Analog Output Voltage Setting
The internal A/D reference voltage can be set to –5V or –10V by JP3.
The possible configurations are specified as Figure 2.5. Note that the
internal reference voltage is used only when the JP4 is set to internal
reference only.
Reference Voltage is
-5V (default setting)

Figure 2.5 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.
