STPM33 : VREF1 and VREF2

[carton]

Hi,

I'm working on a design with a STPM33. The application only needs to measure current on a single phase but, as STPM33 seems cheaper than STPM32, this was the chosen IC.

  

Could I remove C27 and C28 if the second channel is not used? If yes, could I let the VREF2 floating or should I do something with it?

Thanks for your help.
