Depending on the MCU pin count, the package may feature separate V
analog power supply pins. These pins supply power to the A/D converter cell and function
as the high and low reference voltages for the conversion. In some packages, V

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
