Note 1: Tlow = 0°C, Thigh = +70°C
Note 2: The deviation parameter
Vref is defined as the differences between the maximum
and minimum values obtained over the full operating ambient temperature range
that applies.
Vref = VrefMax
–VrefMin
TA = T2–T1
Note 2: (cont’d) The average temperature coefficient of the reference input voltage,
α Vref, is
defined as:
α Vref

α Vref can be positive or negative depending on whether Vref Min or Vref Max occurs at the lower
ambient temperature.
