Hi Folks,
Now that version 1 of my project is done, I am redesigning it after tips obtained here. One of the things I am paying more attention to are the voltage dividers and resistors for op-amps and using only 1%resistors for those parts.
What is the difference between a 1% and 5% resistor? Is it the value or the amount of drift?
I have some 5% ones which are exactly 10k and a 1% one which is slightly below 10k. Is that just luck and I would find that the 5% one would drift over time / temperature?
Drift would be the biggest issue because I can adjust the base-line values in code.
The 1% are metal film and the 5% are carbon film.
Cheers,
Crispin
