Note:
12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 51 are preliminary values derived
from tests performed under the ambient temperature, fPCLK2 frequency and VDDA supply
voltage conditions summarized in Table 9.
It is recommended to perform a calibration after each power-up.
