Switching from Mega to Teensy

Hi There,
I hope you can advise me.
I'm about to add a teensy 4.1 to my project to add usbmidix4 capability.
Since I use an Arduino Mega now, I am new to the Teensy scene.

But I have a very important feature of the Mega that I use right now:
I use 8 analog inputs which all require to handle fader inputs from 0V to 5V, and I need to read the full range of the faders. This voltage is fed from an external device so I can't change this. These fader values are converted to midi values.

My question is:

Is there a way to get these 5v analog inputs into a Teensy (which supports USB MIDIx4) without blowing it up. (I read in the specs that the digital inputs are 3.3V, but I see no specs on the analog inputs).
OR
Is it an alternative to use an external adc shield that handles 5v input and beeps out 3.3V digital.
OR
can I convert the 0V to 5V analog input to a 0V to 3.3V analog input without cutting off the range.
OR
I don't know, maybe you have another option for me... :)


Well, I hope you can help me out on this and I can join the club.

Best,
Fertje.
 
Usually resistors can be used to divide the voltage range down, if whatever is creating that voltage is able to drive the extra load of those resistors.
 
Good Heavens, this machine is incredible.
(Unplugged the Mega and never looking back).
Thank you!
