Characteristics of D/A conversion
1.
Voltage output
The following figure illustrates the characteristic of the D/A conversion (voltage output).
The D/A conversion module is used to convert a digital value from CPU to analog value
for an external device. When the voltage output range of D/A conversion module is -
10~10V, and the input digital value is 0, the output is -10V. If the digital input is 16000,
the output is 10V, where analog value converted from digital input of 1 is equivalent to
1.25mV.
