Limits are 100% production tested at 25 °C. Behavior at the temperature range limits is guaranteed through correlation and by design. 2. See definition below.
Definition of output voltage change over temperature range
Vref is defined as the difference between the maximum and minimum values obtained over the full temperature range. Vref = Vref max - Vref min
