AMSREF-01

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

0.1

µF disk ceramic capacitor.
