Hi, Greetings!!We have been using STM32F446RE MCU in the project. We have implemented the DAC in the application at pin PA4 and PA5. Both DACs are generating similar voltages for different application. The PA4 DAC is connected to ADC of another MCU t...

We tried changing the wire from PA4 to PA5. PA5 is working as expected. Changing the DAC voltage at PA5. Whereas the PA4 status is same, i.e. @2.4V even if the wire is disconnected from PA4 and measured the signal at the pin.

Hi,Thanks for the suggestion.I do agree that the error is because of hardware. The things were working well for couple of months.. So I am curious why this might have happened and what will be the precautions that we should take to avoid this againTh...
