bit) accuracy does not meet the accuracy specified
in the data sheet.
Workaround
In order to have the accuracy specified in the da-
tasheet, the first conversion after a ADC switch-on
has to be ignored.
16.2.11 Negative injection impact on ADC
accuracy
Injecting a negative current on an analog input
pins significantly reduces the accuracy of the AD
Converter. Whenever necessary, the negative in-
jection should be prevented by the addition of a
Schottky diode between the concerned I/Os and
ground.
170/172
Injecting a negative current on digital input pins
degrades ADC accuracy especially if performed
on a pin close to ADC channel in use.
16.2.12 ADC conversion spurious results
Spurious conversions occur with a rate lower than
50 per million. Such conversions happen when the
measured voltage is just between 2 consecutive
digital values.
Workaround
A software filter should be implemented to remove
erratic conversion results whenever they may
cause unwanted consequences.
