Hello everybody,

 

I am looking for a way to conect the Max10 internal reference voltage to some output pin. Can this be done?

We have Reference Voltage Pin (VREF) available in MAX10. However, it is meant for some I/O Bank that requires reference voltage for input operation.

Thank you for your reply. Maybe my question was a bit vague.

I would like to output the internal Vref voltage to be accessed by some external cicuit.

It is not possible as the vref input pin is used for IO buffer. May i know what is the reason to ouput vref voltage to external device?

Just to use 2.5V reference voltage for the OpAmp input.

If it so, i would suggest to use 1 of the I/O pin to supply a constant 2.5V to the OpAmp input.
