changes of the analog input voltage have no effect on the conversion result. Values for the

sample clock tS depend on programming.

(1) Data based on characterisation results, not tested in production.

(2) ADC accuracy vs. negative injection current: Injecting negative current on any of the

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 standard analog pins which may potentially inject negative current.
