Functional Description
(Continued)
Adjusting for an Arbitrary Analog Input
Voltage Range
If the analog zero voltage of the A/D is shifted away from
ground (for example, to accommodate an analog input signal
which does not go to ground), this new zero reference
should be properly adjusted first. A V
IN
(+) voltage which
equals this desired zero reference plus
1
2
LSB (where the
LSB is calculated for the desired analog span, using 1 LSB =
analog span/256) is applied to selected “+” input and the
zero reference voltage at the corresponding “” input should
then be adjusted to just obtain the 00
HEX
to 01
HEX
code
transition.
The full-scale adjustment should be made [with the proper
V
() voltage applied] by forcing a voltage to the V
IN
(+)
input which is given by:
Applications
where:
V
MAX
= the high end of the analog input range
and
V
MIN
= the low end (the offset zero) of the analog range.
(Both are ground referenced.)
The V
IN (or V
) voltage is then adjusted to provide a
code change from FE
HEX
to FF
HEX
. This completes the
adjustment procedure.
