DAC714
FIGURE 1. DAC714 Block Diagram.
OUTPUT VOLTAGE SWING
The output amplifier of the DAC714 is designed to achieve
a
±
10V output range while operating on
±
11.4V or higher
power 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%.
FIGURE 3. Relationship of Offset and Gain Adjustments.
Offset Adjustment
Apply the digital input code, 8000
H
, that produces the maxi-
mum negative output voltage and adjust the offset potentiometer
or the offset adjust D/A converter for –10V (or 0V unipolar).
