RM0008 Digital-to-analog converter (DAC)
185/690
Figure 39. DAC channel block diagram
Note: Once the DAC channelx is enabled, the corresponding GPIO pin (PA4 or PA5) is
automatically connected to the analog converter output (DAC_OUTx). In order to avoid
parasitic consumption, the PA4 or PA5 pin should first be configured to analog (AIN).
