3.4 Characteristic of I/O Conversion
Characteristic of I/O conversion converts a digital input into an analog output (voltage, current) and
displays a straight line with the gradient as shown below. The range of digital input is shown with
Unsigned Value, Signed Value, Precise Value, and Percentile Value such as the graph below.
