Analog-to-Digital converter characteristics

Unless otherwise specified, the parameters given in Table 66 are preliminary values derived

from tests performed under ambient temperature, fPCLK frequency and VDDA supply voltage

conditions summarized in Table 20: General operating conditions.

Note:

It is recommended to perform a calibration after each power-up.
