32.6 Application information
This section contains information for using the ADC module in applications. The ADC
has been designed to be integrated into a microcontroller for use in embedded control
applications requiring an ADC.
32.6.1 External pins and routing
The following sections discuss the external pins associated with the ADC module and
how they should be used for best results.
32.6.1.1 Analog supply pins
The ADC module has analog power and ground supplies (V
DDA
and V
SSA
) available as
separate pins on some devices. V
SSA
is shared on the same pin as the MCU digital VSS
on some devices. On other devices, V
SSA
and V
DDA
are shared with the MCU digital
