Hi all,
I will be using a potentiometer to output voltage as close to 13mV steps. I want the potentiometer to output the same voltage even when the system is reset or when other loads are connected to the same power line.
To help achieving this I was planning to connect one terminal of the pot to a 4.7V zener diode instead of connecting it directly to the 5V supply. This way if a voltage drop occurs (when connecting other loads or for any other reason), the voltage to the pot will remain stable.
Will this work? is it possible to have a repetitive output voltage as close as 13mV?
