Parameter definitions
Reference input voltage deviation over temperature range
ΔVref is defined as the difference between the maximum and minimum values obtained over
the full temperature range.
ΔVref = Vref max. - Vref min.

Reference input voltage deviation over temperature range
Temperature coefficient of reference input voltage
The temperature coefficient is defined as the slopes (positive and negative) of the voltage
versus temperature limits within which the reference is guaranteed.
