5.1.1
Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at T = 25 °C and T = T max (given by

the selected temperature 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 minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).

5.1.3
Typical values
Unless otherwise specified, typical data are based on T = 25 °C, V = 3.3 V (for the
A
DD
1.8 V ≤ V ≤ 3.6 V voltage range). They are given only as design guidelines and are not
DD
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±2Σ).
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
