NUCLEO-H753ZI voltage output

Hello,

 

Can I output an adjustable voltage ranging from -10V to 10V using the h753zi development board?

 

I found something like a "PWM to 0-5V/10V DAC Module."

Would I need to use such an external module or build an additional circuit externally to achieve this?

 

I would appreciate your advice and look forward to your response.

 

Thank you!

As the entire NUCLEO board operates with a positive voltage, a negative output voltage can only be achieved with external circuitry, which in turn also requires a negative supply voltage.

So yes, for ±10V you would have to connect a level shifter, e.g. using opamps.

Hope that helps?

Regards
