9.6
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 A/D
converter.
9.6.1
The following sections discuss the external pins associated with the ADC module and how they should be
used for best results.
9.6.1.1
The ADC module has analog power and ground supplies (V
separate pins on some devices. On other devices, V
and on others, both V
are separate pads for the analog supplies which are bonded to the same pin as the corresponding digital
supply so that some degree of isolation between the supplies is maintained.
When available on a separate pin, both V
as their corresponding MCU digital supply (V
noise immunity and bypass capacitors placed as near as possible to the package.
