that(Vin+) + (Vin–) added to the gain times (Vin+) –(Vin–) must be with in
±26 V of AIGND. At gains of 10 and 100, this is roughly equivalent to
restricting the two input voltages to within ±8 V of AIGND.
Analog Output Signal ConnectionsThe AO signals are DAC0OUT, DAC1OUT, EXTREF, and AOGND.
Note DAC0OUTand DAC1OUT are not available on the AT-AI-16XE-10.EXTREF is
not availableon the AT-MIO-16XE-10, AT-AI-16XE-10,or AT-MIO-16XE-50.
DAC0OUTis the voltage output signal for AO channel 0. DAC1OUT is the
voltageoutput si gnal for AOchannel 1.
EXTREFis the externalreference inpu tf orb oth AOchannels. You must
configureeach AO channel individually for external reference selection in
orderfor the signal applied at the external reference input to be used by that
channel.If you do not specify an external reference, the channel uses the
internalreference.
Note Youcannot use an external AO reference with the AT-MIO-16XE-10,
AT-AI-16XE-10,or AT-MIO-16XE-50.
AOconfiguration options are explained in the Analog Output section of
Chapter3, HardwareOverview.
AOGNDis the ground reference signal for both AO channels and the
externalreference signal.
Figure 4-10 showshow to make AO connections and the external reference
input connection to the ATE Series device.
