    Hello everyone
    I am currently working on a DSP drive that uses (just found out) two different brands of resistors
    same specifics 6k 25ppm (one is a Panasonic the other TE)
    since I am experiencing some issues (the circuit is very sensitive)
    I thought that it might be that the two resistors are behaving in two different ways
    like one is -25 while the other is going +25
    so the divisor component fails the math
    thanks

    What type of circuit is sensitive to a 25ppm temp coefficient for the resistors?
    More details please.
