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 = TA(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).

5.1.2

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 22.

5.1.5

Pin input voltage

The input voltage measurement on a pin of the device is described in Figure 23.

5.1.6

Power supply scheme

Each power supply pair (such as VDD/VSS or VDDA/VSSA) must be decoupled with filtering ceramic capacitors as

shown in the following figures. These capacitors must be placed as close as possible to, or below, the appropriate

pins on the underside of the PCB to ensure the proper functionality of the device.
