ADDAC80/ADDAC85/ADDAC87
Offset Adjustment
For unipolar (CSB) configurations, apply the digital input code
that should produce zero potential output and adjust the
OFFSET potentiometer for zero output. For bipolar (COB, CTC)
configurations, apply the digital input code that should produce
the maximum negative output voltage. Example: If the FULL
SCALE RANGE is connected for 20 V, the maximum negative
output voltage is –10 V. See Table II for corresponding codes.
Gain Adjustment
For either unipolar or bipolar configurations, apply the digital
input that should give the maximum positive voltage output.
Adjust the GAIN potentiometer for this positive full-scale voltage.
See Table II for positive full-scale voltages.
