Figure 43. DAC channel block diagram
1. In connectivity line devices, the TIM8_TRGO trigger is replaced by TIM3_TRGO .
Table 68.
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).
