(1) Functional test.
(2) The average temperature coefficient is defined as the maximum deviation of reference voltage, at all measured temperatures between
the operating T_Min & T_Max, divided by (T_Max − T_Min). The measured temperatures (T_Measured) are −55°C, 25°C, & 125°C or ΔV_Ref / (T_Max −
T_Min)
