    Hi

    Can I reply on the output of a regular trimpot to remain the same value over a range of temperature and time.

    My understanding is, it's just like a two-resistor voltage divider, but those two resistors are made of same material, so their temperature coefficient and aging should be at the same rate.

    Hence the ratio of those two resistors value will be the same over a range of temperature and time?
