1. Limits are 100% production tested at 25°C. Behavior at the temperature range limits is guaranteed through correlation and
by design.

Definition of output voltage change 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
