1. Guaranteed by design
2. The I/O analog switch voltage booster is enabled when VDDA < 2.4 V (BOOSTEN = 1 in the SYSCFG_CFGR1 when
VDDA < 2.4V). It is disabled when VDDA ≥ 2.4 V.
3.
VREF+ can be internally connected to VDDA, depending on the package.
Refer to Section 4: Pinouts and pin description for further details.
4. The maximum value of RAIN can be found in Table 70: Maximum ADC RAIN.
