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