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 ppm =

∆TA
= ∆TA (Vref @ 25°C)

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