I am using STM32G474VET3 controller.
As i am using DAC out voltage for my application.
So i want to know the DAC output stability, performance over temperature, & the temperature drift at Maximum junction temperature 150 °C.
Also any other factors affecting my DAC out.
Also how to mitigate this deviation in DAC out reading at normal room temperature to Max highest ambient temperature ambient temperature 150 deg C
Solved! Go to Solution.

Primarily, the accuracy and temperature drift will depend on your VREF+ accuracy and temperature drift. If you're using the internal VREFBUF, then you can see its performance specification in the datasheet.
Nonlinearity and other accuracy specs can be found in the datasheet:

Max junction temperature seems to be 130 C from the datasheet.
