2.5 Analog Output Signal Connection
An analog output channel generates a voltage output to the load. The voltage to be
generated is first sent by the internal controller to the digital-to-analog converter
(DAC) in a form of digital data, and the data is converted by the DAC to an analog
output voltage. The analog output channel is of single-ended type, hence the load
should be connected between the analog output (AO) terminal and the analog
ground (AGND) terminal. This is shown in Figure 2.7.
Figure 2.7 Analog output signal connection.
Multiple output ranges are supported and can be selected by software for each chan-
nel independently. Be sure that the load resistance is within the range of the device
specifications, or the output voltage may not reach the specified value due to the lim-
itation of output driving capability.
The output range can also be defined by an external reference voltage which is con-
nected to the analog output reference (AO_REF) terminal. Refer to the device speci-
fications for the relationship between the output range and the external reference
voltage. In this configuration, however, the output voltage is not calibrated, and the
accuracy of the output voltage depends on the accuracy of the external reference
voltage. Users can perform calibration through the calibration utility in the Advantech
Navigator by themselves.
2.5.1 Analog Output Reference Voltage Input
If desired, an external voltage source can be connected to the reference voltage input
terminal to use a user-defined output range. When a “x V” voltage is applied, output
range can be configured as 0 V ~ x V or –x V ~ x V.
