    Hi,
    Does anyone know of a IC which can substitute the LM308? Need this for a IR project I'm working on. Fast answers are greatly appreciated...

    isnt the 308 a quad op amp? tho at college we used 741 and 108 without worrying which it was really (tho pinout might be different) *shrugs* we just looked up the pinout when we needed em

    Yep, an op amp. So you think I could use the 741, then? I have datasheets of both, so the pinouts aren't a problem. :clap:

    u may have to rearrange the pinouts and will definitelyu if u r moving from 308 to 741 because a 308 has 4 op amps in it and a 741 has 1 op amp in it ok?

    and i think they actual specs of the op amps are similar but i cant remember too well

    best look at the datasheets yerself and work it out

    It's a bit more upmarket than a 741, so tread wary.

    the 108 is a better ic probably better response over different temps / frequencys

    if your doing stuff that requires a high quality signal where the shape / amplification ammount matter a lot use 108. if on the other hand it dosent matter too much about the quality of the signal or accuracy (led temp sensors etc) then go cheep :)

    hmmm sorry im not so good at explaining

    Not good at explaining? I understood pretyy clear what you meant. Could I substitute the 308 with a 108/208, then?

    108, 208 and 308 are all about the same specs, just the first is single, second dual and third a quad package.

    Full spec

    Ok, so I just went through Elfa's online catalog of op amps again. I turns out they have none of the LMx08's!?! I think that's too bad. Does anyone know of a place which sells these to Norway (online) with good prices, and not to high shipping?
