Electrical characteristics

5.1

Parameter conditions

Unless otherwise specified, all voltages are referenced to VSS.

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 TA = 25 °C and TA = TAmax (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).

5.1.2

Typical values

Unless otherwise specified, typical data are based on TA = 25 °C, VDD = VDDA = 3 V.

They are given only as design 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 and supply voltage range, where

95% of the devices have an error less than or equal to the value indicated (mean ±2σ).

5.1.3

Typical curves

Unless otherwise specified, all typical curves are given only as design guidelines and are

not tested.

5.1.4

Loading capacitor

The loading conditions used for pin parameter measurement are shown in Figure 21.

5.1.5

Pin input voltage

The input voltage measurement on a pin of the device is described in Figure 22.
