Typical Applications

3. The auto-zero/auto-full-scale (See Figures 5–8) should
use double precision, rounded (as opposed to truncated)
arithmatic. Several points are worth noting:
a. The subtractions are single op code instructions.
b. The full scale correction uses a multiply by 256 and
can be accomplished by a shift left 8 bits (usually one
instruction) or placing (N

) in the MSB register
and setting the LSB register to zero, for the double
precision divide.
c. The divisor (N

) of the MSB register will al-
ways be zero.
These schemes have the following advantages:
a. No access to the data bus or address bus is required,
by the A/D system.
b. 5 I/O bits completely support the A/D system.
c. Since auto full scale/auto zero are implemented in
software and long term drift (aging) effects are elimi-
nated.
d. Software overhead is minimal (typically 30 bytes).
e. Where ratiometric operation is permissible, the 4 exter-
nal components may be
