*: VDD is the device power supply while AVDD is the ADC power supply. The AVDD pin is bonded together
internally with VDD.
**: VSS is the device ground pin while AVSS is the ADC ground pin. The AVSS pin is bonded together
internally with VSS.
As the Pin Description Summary table applies to the package type with the most pins, not all of the above listed
pins may be present on package types with smaller numbers of pins.
