Electrical characteristics
STM32F410x8/B
Note:
ADC accuracy vs. negative injection current: injecting a 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 currents.
Any positive injection current within the limits specified for I_INJ(PIN) and ΣI_INJ(PIN) in
Section 6.3.16 does not affect the ADC accuracy.
