Analog Output Configuration

You can select different analog output configurations by using the jumper settings shown in
Table 2-5. The following paragraphs describe in detail each of the analog output configurations.

Analog Output Reference Selection

Each DAC can be connected to the AT-MIO-16D internal reference of 10 V or to the external
reference signal connected to the EXTREF pin on the I/O connector. This signal applied to
EXTREF must be between -10 V and +10 V. Both channels need not be configured the same
way.

External Reference Selection

You select the external reference signal for each analog output channel by setting the following
jumpers:
Analog Output Channel 0:
Analog Output Channel 1:
This configuration is shown in Figure 2-15.

Internal Reference Selection (Factory Setting)

You select the onboard 10 V reference for each analog output channel by setting the following
jumpers:
Analog Output Channel 0:
Analog Output Channel 1:
This configuration is shown in Figure 2-16.
