20 SILICON LIMITATIONS

20.1 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 injection should be prevented by the addi-

tion of a Schottky diode between the concerned I/Os and ground.

Injecting a negative current on digital input pins degrades ADC accuracy especially if per-

formed on a pin close to ADC channel in use.
