3.4 Analog Output Connections
The PCI-1710/1710HG/1711/1716 provides two D/A output channels
(PCI-1710L/1710HGL/1711L/1716L are not designed to have this
function), AO0_OUT and AO1_OUT. Users may use the PCI-1710/
1710HG/1711/1716 internally-provided precision -5V (-10V) reference to
generate 0 to +5 V (+10 V) D/A output range. Users also may create D/
A output range through external references, AO0_REF and AO1_REF.
The external reference input range is +/-10 V. For example, connecting
with an external reference of -7 V will generate 0 ~ +7 V D/A output.
Figure 3-5 shows how to make analog output and external reference
input connections on the PCI-1710/1710HG/1711/1716.
