ADC accuracy vs. negative injection current
Injecting negative current on specific pins listed in Table 46 (generally adjacent to the analog
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.
Figure 42.
Typical application with ADC
Analog power supply and reference pins
The VDDA_ADC and VSSA_ADC pins are the analog power supply of the A/D converter cell.
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 : General PCB design
guidelines on page 74).
