Hello. I need to implement a way to achieve 0-10V analog output controlled by 0 - 3.3V logic from the microcontroller. I have got acces to higher voltage supply which I can step down to +10 or +12V if required.
The only sensible option I can think of is to use DAC. From the microcontroller datasheet:
https://www.st.com/resource/en/datasheet/stm32f051t8.pdf
It is mentioned about in-built 12-bit DAC but I am not sure if i can implement it for 0 -10V?
Another option I see is to built an R2R ladder or use DAC chip but I am not sure if I have that many GPIO pins available lets say 8 GPIO for 8-bit converter.
Any suggestions pleae?
