12 ELECTRICAL CHARACTERISTICS
12.1 PARAMETER CONDITIONS
Unless otherwise specified, all voltages are re-
ferred to V
12.1.1 Minimum and Maximum values
Unless otherwise specified the minimum and max-
imum values are guaranteed in the worst condi-
tions of ambient temperature, supply voltage and
frequencies by tests in production on 100% of the
devices with an ambient temperature at T
and T
range).
Data based on characterization results, design
simulation and/or technology characteristics are
indicated in the table footnotes and are not tested
in production. Based on characterization, the min-
imum and maximum values refer to sample tests
and represent the mean value plus or minus three
times the standard deviation (mean±3 ).
12.1.2 Typical values
Unless otherwise specified, typical data are based
on T
sign guidelines and are not tested.
Typical ADC accuracy values are determined by
characterization of a batch of samples from a
standard diffusion lot over the full temperature
range, where 95% of the devices have an error
less than or equal to the value indicated
(mean±2 )
12.1.3 Typical curves
Unless otherwise specified, all typical curves are
given only as design guidelines and are not tested.

measurement are shown in
