Applications Information
(Continued)
LSB is calculated for the desired analog span, 1 LSB = ana-
log 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
(+) in-
put which is given by:
where V
=the high end of the analog input range and
V
=the low end (the offset zero) of the analog range. (Both
are ground referenced.)
The V
(or V
CC
) voltage is then adjusted to provide a code
change from FE
HEX
to FF
HEX
. This completes the adjust-
ment procedure.
For an example see the Zero-Shift and Span Adjust circuit
below.
