ELECTRICAL SPECIFICATIONS
Note 1:
The deviation parameters, Vref(dev) and Iref(dev)
are defined as the differences between the maximum
and the minimum values obtained over the rated tem-
perature range. The average full range temperature coef-
ficient of the reference input voltage is defined as:
Where:
'α
Vref
'
unit is ppm/
$
C
T
A
is the rated operating free air temperature of the
device.
α
Vref can be positive or negative depending on whether
minimum Vref or maximum Vref respectively occurs at
the lower temperature.
