AMSREF-02

TYPICAL APPLICATIONS

±± 5V Reference

Supply Bypassing

For best results, it is recommended that the power supply pin is bypassed with a

0.1

µF disk ceramic capacitor.

OUTPUT ADJUSTMENT

The REF-02 trim terminal can be used to adjust the 5 Volt output

voltage

± 300mV. This feature allows the system designer to trim

system errors by setting the reference to a voltage other than 5V.

The system can also be set exactly 5.000V, or to 5.12V 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.
