Analog I/O is related to continuous voltage/current value and digital
value. The acceptable I/O value is defined as a line within a distance
of the minimum 1LSB of voltage/current. I/O linearity error is
regarded as the deviation between the acceptable-converted value
and the actual-converted value on the graph. See the following
figure.
A switching circuit where many signals share one A/D converter or
D/A converter.
A module with output circuit to convert digital value from the process
to analog output (voltage/current).
The minimum value recognizable by a measuring instrument, which
is usually displayed in the engineering unit (1mV) or the number of
bits. So when there are 14 bits, 16383 output values can be
generated.
Filters are used to avoid sudden changes in the digital value output
caused either by external noise or sudden change in the analog
input signal. Two types of filters used are: S/W and H/W
