Output Adjustment
The REF02 trim terminal can be used to adjust the out-
put voltage over a 5V±300mV range. This feature
allows the system designer to trim system errors by set-
ting the reference to a voltage other than 5V (refer to
the
Typical Operating Circuit
section).
Adjustment of the output does not significantly affect
the temperature performance of the device. Typically,
the temperature coefficient change is 0.7ppm/°C for
100mV of output adjustment.
Temperature Voltage Output
The REF02 provides a temperature-dependent output
voltage on the TEMP pin. This voltage is proportional
to the absolute temperature, and has a scale factor of
approximately 2.1mV/°C (Figure 2).
Output Voltage = 2.1(T + 273)mV
where T = Temperature in °C
