STM32G4 without VSSA pin

[Liann1]

I'm using the STM32G431CBU3 in a project that shares the same ground for digital and analog supplies, but the UFQFPN-48 package doesn't have a VSSA pin like the others. What should I do in this situation? Should I consider VREF as my VSSA?

No doubt VSS is bonded internally to VSSA/VREF-. Grounds must all be tied together, they are not independent.

Dear @Liann1 ,

VREF+ is used for the positive voltage ,  you can connect to VDDA if you do not need a precise ADC conversions .  As said by @TDK  All analog and digital grounds including VSSA are bonded at package level to a common VSS.

Hope it helps
