The PCI-1710U/HGU/UL provides two D/A output channels. You can
use the internal precision -5 V or -10 V reference to generate 0 to +5 V or
0 to +10 V D/A output. Use an external reference for other D/A output
ranges. The maximum reference input voltage is ±10 V and maximum
output scaling is ±10 V. Loading current for D/A outputs should not
exceed 5 mA.
