OUTPUT VOLTAGE SWING
The output amplifier of DAC712 is committed to a
±
10V
output range. DAC712 will provide a
±
10V output swing
while operating on
±
11.4V or higher voltage supplies.
GAIN AND OFFSET ADJUSTMENTS
Figure 3 illustrates the relationship of offset and gain adjust-
ments for a bipolar connected D/A converter. Offset should
be adjusted first to avoid interaction of adjustments. See
Table I for calibration values and codes. These adjustments
have a minimum range of
±
0.3%.

Offset Adjustment
Apply the digital input code that produces the maximum
negative output voltage and adjust the offset potentiometer
or the offset adjust D/A converter for –10V.
