The deviation parameters ΔVREF/ΔT and ΔIREF/ΔT are defined as the differences between the maximum and
minimum values obtained over the recommended temperature range. The average full-range temperature
coefficient of the reference voltage, αVREF, is defined as :
(
VI(dev)
) × 106
αVREF (ppm/℃) =
VREF at 25℃
ΔTA
Where :
ΔTA is the recommended operating free-air temperature range of the device.
