Hi all
I'm working on a proyect involving readings from several potentiometers with Teensy 3.2. Everything works fine, but now I'd like to improve precission. As far as I know the Teensy 3.2 ADC is default set to 10 bit, but I'd like to use 12 or even 13 bits.
In order to do that I'm thinking about:
- A more stable voltage reference attached to AREF pin than the internal reference.
- A stable Vcc applied to the potentiometers.
I'be never worked with this kind of IC's. Is any voltage reference IC recommended for this? Also, would it be a good idea to use the same voltage reference output to feed all the potentiometers, or is better to use the 3.3v regulator inside the Teensy for the potentiometer rail?
Thank you!
