The formula for the voltage output versus digital code for a bipolar
analog output configuration in two's complement form is as follows:
V
= V
* (digital code)
out
ref
where V
is the positive reference voltage applied to the analog output
ref
channel. The digital code in the preceding formula is a decimal value
ranging from –32,768 to +32,767.
