I need a stable voltage reference for my Teensy’s analog inputs ADC using the board’s AREF pin. I have a Pololu boost converter providing 5v to the Teensy and to other parts.
I plan to use the boost converter’s output as a reference for my AREF pin too, possibly through a voltage divider. Will it be stable and clean enough or should I use a shunt regulator (such as a TL431 for instance) for this purpose instead ?
Thank you in advance.
