Figure 12. Output Adjustment
The REF01 trim terminal can be used to adjust the output
voltage over a 10 V ± 300 mV range. This feature lets the
system designer trim system errors by setting the reference
to a voltage other than 10 V. The output also can be set exactly
to 10.000 V or to 10.240 V for binary applications.
Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature
coefficient change is approximately 0.7 ppm/°C for 100 mV
of output adjustment.
