1. Guaranteed by design.

2. ADC DC accuracy values are measured after internal calibration.

3. ADC accuracy vs. negative Injection Current: Injecting negative current on any analog input pins should be avoided as this

significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a

Schottky diode (pin to ground) to analog pins which may potentially inject negative current.

4. The I/O analog switch voltage booster is enable when VDDA < 2.4 V (BOOSTEN = 1 in the SYSCFG_CFGR1 when

VDDA < 2.4 V). It is disable when VDDA ≥ 2.4 V. No oversampling.
