ADC accuracy vs. negative injection current
Injecting negative current on specific pins listed in
input pin being converted) should be avoided as this significantly reduces the accuracy of
the conversion being performed. It is recommended to add a Schottky diode (pin to ground)
to pins which may potentially inject negative current.

Separation of the digital and analog power pins allow board designers to improve A/D
performance. Conversion accuracy can be impacted by voltage drops and noise in the event
of heavily loaded or badly decoupled power supply lines (see
