    Hello :)

    I have started studying about op amps recently and what I have understood is that an OP AMP is basically just a really large resistor which can manipulate the direction of the flow of current. Is this correct. The gain is controlled by the resistors connected to the OP AMP. If this is the case then why do the data sheets of OP AMPS have a value for " large signal voltage gain" in them?? :confused:

    Looking forward to all the clever answers!

    No, an op amp is a high gain differential amplifier. That is quite different than a resistor.
