A project I am building requires an LM627N Op Amp. I can't find this device in the Element 14 catalog. Is there an equivalent type that I can look for?

 

Thank you.

    I can't seem to find anything on this chip.  Do you have a data sheet you could post for it? Or could you possibly post a schematic or something for the project?

    I have a datasheet but it is in Chinese. You may be able to make sense of it by looking at the block diagram. If noy I can send you data on the project.

     

    Regards

    Ok, well ive found a couple things.  First off while just going through google searches it seemed that it came up alot that an OP27GPZOP27GPZ could replace it...??? Im not 100% sure of this, as the ones i have looked up are not exactly the same as in your data sheet.  From looking at the datasheet I can tell you a few things (It being in chinese I cannot guarentee all of these, but im pretty sure);

     

    1. It is an 8 pin DIP Op Amp (Im sure you already knew this)

    2. It has a single comparator

    3. The supply voltage is 15V (optimal) (3.5V to 18V operating range (not sure???))

    4. The slew rate is 4.5V/us

     

    If you go on whatever website you use to get parts and put in these parameters you may be able to find something similar.
