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.
