Application Hints

ZERO AND FULL-SCALE ADJUSTMENT
Zero Adjustment:
This is the offset voltage required at the
bottom of the R-network (pin 5) to make the 11111111 to
11111110 transition when the input voltage is
(/2
LSB (20
mV for a 10.24V scale). In most cases, this can be accom-
plished by having a 1 k
X
pot on pin 5. A resistor of 475
X
can be used as a non-adjustable best approximation from
pin 5 to ground.
Full-Scale Adjustment:
This is the offset voltage required
at the top of the R-network (pin 15) to make the 00000001
to 00000000 transition when the input voltage is 1
(/2
LSB
from full-scale (60 mV less than full-scale for a 10.24V
scale). This voltage is guaranteed to be within
g
2 LSB for
the ADC0800 without adjustment. In most cases, adjust-
ment can be accomplished by having a 1 k
X
pot on pin 15.
