Reference input voltage deviation over temperature range
ΔV_ref is defined as the difference between the maximum and minimum values obtained over
the full temperature range.
ΔV_ref = V_{ref max.} - V_{ref min.}

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.
