41.5.9 Analog Connections

Each OPAMP has two I/O pins that can be used as analog inputs. These pins must be configured for analog operation before using them as OPAMP inputs.

If the DAC is to be used as OPAMP input, the DAC must be configured and enabled first.

Each OPAMP has one I/O pin that can be used as analog output. This pin must be configured for analog operation before using it as OPAMP output.

The analog signals of AC, ADC, DAC and OPAMP can be interconnected. The AC and ADC peripheral can request the OPAMP using an analog ONDEMAND functionality.

See Analog Connections of Peripherals for details.
