is tehre any simple way to create 5v tolerant ADC input on STM32H750?

[BHell.1]

I have seen an example to create 5v tolerant input on STM32H750, a resistor divider controlled by GPIO. Now I can't find find it when I need it...anyone seen this example and maybe can point it out?

I suppose I need a buffer in front to avoind impedance matching problems?

thanks

1. 2 resistors = a resistor divider
2. buffer in front - only, if your divider cannot be driven by the source
