    Dear members,

    I have designed this inverting amplifier, and I wish to ask if I did the trimmer good to reduce offset voltages. Does using this trimmer mean I will be reducing offset voltages? Is this the way the LM741 would be configured also? Thanks in advance, hope to hear from you soon,
    Regards

    The trimmer is supposed to compensate the offset voltage and the resistors in the non-inverting pin for the input bias current.

    However, every OpAmp has a slightly different application method, so I suggest you read the datasheet of the OpAmp you have.
