Analog Output Signal Connections
The analog output signals are DAC0OUT, DAC1OUT, EXTREF, and
AOGND. EXTREF is not available on the PCI-MIO-16XE-10 or
PCI-MIO-16XE-50.
DAC0OUT is the voltage output signal for analog output channel 0.
DAC1OUT is the voltage output signal for analog output channel 1.
EXTREF is the external reference input for both analog output
channels. You must configure each analog output channel individually
for external reference selection in order for the signal applied at the
external reference input to be used by that channel. If you do not specify
an external reference, the channel will use the internal reference. You
cannot use an external analog output reference with the
PCI-MIO-16XE-10 or PCI-MIO-16XE-50. Analog output configuration
options are explained in the Analog Output section in Chapter 3,
Hardware Overview. The following ranges and ratings apply to the
EXTREF input:
•
Usable input voltage range:
±
11 V peak with respect to AOGND
•
Absolute maximum ratings:
±
15 V peak with respect to AOGND
AOGND is the ground reference signal for both analog output channels
and the external reference signal.
Figure 4-8 shows how to make analog output connections and the
external reference input connection to your PCI-MIO E Series board.
