1. Evaluated by characterization – Not tested in production.
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 enabled when VDDA < 2.4 V (BOOSTEN = 1 in the SYSCFG_CFGR1 when
VDDA < 2.4 V). It is disabled when VDDA ≥ 2.4 V. No oversampling.
