Note:
12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 60 are preliminary values derived
from tests performed under ambient temperature, fPCLK2 frequency and VDDA supply
voltage conditions summarized in Table 22.
It is recommended to perform a calibration after each power-up.
