∆V

REF is defined as the difference between the maximum and minimum values obtained over the full temperature range.

∆V

REF = VREF(MAX) – VREF(MIN)

(2)

The temperature coefficient is defined as the slopes (positive and negative) of the voltage vs temperature limits within which the

reference voltage is specified.
