    opam

    op amp ??
    if yes
    its an amplifier that is more than amplifier
    it is definately used as amp but "operational" is coz u can perform various mathematical perations using it. such as +,-,/,*, log, exp

    The main job for op-amp is amplifier (operation amplifier).

    Re: opam

    opamps contains lots of BJTs and FETs that in a very small scale.

    Re: opam

    opamp are important
    because we can use opamp as
    amplifier - as inverting and non inverting
    comparator - to compare two voltages
    integrator - to intergrate
    differentiator - to differentiate
    filters - low pass,high pass and band pass
    as oscillator

    Re: opam

    we use amplifier simply because we need to amplify small signal to drive certain circuit for a certain application.

    Re: opam

    it is close to an ideal amplifier

    Re: opam

    Hi Friend,

    This is a VLSI technology that involves many BJTs & FETs in-built on a single chip. The main aim is to reduce the Size, Cost & the Complexity of the circuit. This is an IC called IC 741 which can invert your supply and can perform differentiation/integeration when necessary biasing is given.


    Regards,
    Avinash.S.
