Analog-to-digital converter characteristics

Unless otherwise specified, the parameters given in Table 109 are preliminary values

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

voltage conditions summarized in Table 27: General operating conditions.

Note:

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