Correct resistors to convert 5V signal into 3.3V?

[Bullone]

Hi guys,
can you please point me to the best resistors value to acquire an analog signal of 0-5V with Teensy 3.6 board?
I'm thinking to just create a voltage divider but what are the best value for resistors?

10k and 20k would be appropriate. These are common values and you can choose more expensive ones if you need a low temco.

Perfect, thanks!
