Analog Peripherals Considerations

This chapter provides a global view of the analog system, which is composed of the following analog peripherals: AC, ADC, DAC, OPAMP.

The analog peripherals can be connected to each other as illustrated in the following block diagram.

CAUTION: Only one analog output function can be used on the same pin.
Figure 1. Analog Signal Components Interconnections
Note: Some OPAMP Outputs (OAxOUT) can be connected directly to specific Analog Comparator or ADC Inputs (AINx) if they share the same pad, for example, OA0OUT can be connected to the Analog Comparator AIN3 or ADC AIN5 input (PA07 pin).
