    Hi Rejo,

    what is the maximum supply current you can accept?

    Hello Rejo,

    If the maximum supply voltage in the application is +5 V, then a precision op amp such as the OPA333 should be a suitable replacement for the MAX478C/LT2178.

    If the supply is +4.5 to +15 V, the higher supply voltage LMC6061 might be an option:

    However, if the supply voltage requirements are even higher, such as +/-12 or +/-15 V, the OPA241 might be an option:

    These device selections where based on the low operating current requirement. However, we would really need to know what parameters are most important in your application to help select the most suitable op amp.

    Regards, Thomas
