2.5.4 Internal Reference Voltage Setting
The internal reference voltage can be set to either –5V or –10V by JP3. Possible configurations are
illustrated in the table below. Note that the internal reference voltage is used only when JP5 is set
to internal reference only. If –10V internal 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.
