OUTPUT ADJUSTMENT
The REF-01 trim terminal can be used to adjust the 10V output
voltage ± 300mV. This feature allows the system designer to trim
system errors by setting the reference to a voltage other than 10V.
The system can also be set exactly 10.000V, or to 10.240V for
binary applications.
Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature coefficient
change is approximately 0.7ppm/°C for 100mV of output
adjustment.

Supply Bypassing
For best results, it is recommended that the power supply pin is bypassed with a
0.1µF disk ceramic capacitor.
