ADC pin current requirements?

[NNagy.1]

I'm designing a guitar pedal using my F767ZI Nucleo, and I have an input stage current buffer using a TL072 op amp. I'm using the Nucleo's 3.3v as VCC.

I would like to know if I can wire the op amp output pin directly to the ADC pin on the Nucleo, or if I need to regulate the current using resistors. I'm not sure how much current the op amp outputs, nor am I sure how much current the Nucleo can tolerate.

When you power op amp with 3V3 ,then you can connect output directly to ADC, but if op amp have too negative voltage then not.

And ADC sink voltage not current. For safety place 100R
