    Replacement for AD848JR

    I can't find AD848JR (SMD) in local market. It has been used in a pre-amplifier circuit and since it is burned I need to replace it. Any suggestion for replacement?

    thx

    Re: Replacement for AD848JR

    There's probably no exact replacement for this high speed OP. If I would suggest any, you'll surely tell me that it's neither available at your site.

    Instead you should analyze the detail requirements demanded by the application, e.g. GBW, slew rate, supply voltage, output swing and current capability, input impedance, offset and noise. Then check if there's a more common OP that can replace AD848 in this application.
