List of operations that can be made out using Opamp (Operation Amplifier)

1. Inverting Amplifier

    Inverting Amplifier is a configuration of OpAmp that inverts and boosts the input.

Notable Formulas:

Gain = Rf/Rin

Vout     Rf

------ = -----

Vin       R1

2. Non - Inverting Amplifier

    Non - Inverting Amplifier is a configuration of OpAmp that boost the input

Notable Formulas:

Vout             Rf

------ = 1 + -------

Vin               R1

3. Differential Amplifier

    Differential Amplifier is a configuration of OpAmp that subtracts the inputs

 

Notable Formulas:

Vout     Rf

------ = -----

Vin       R1

4. Summing Amplifier

     Differential Amplifier is a configuration of OpAmp that sums the inputs

Notable formulas:

Vo = Rf((V1/R1) + (V2/R2) + ... + (Vn/Rn))

if R1 == R2 == ... == Rn == R:

Vo = -Rf/R(V1 + V2 + ... + Vn)

if R1 == R2 == .. == Rn == R == Rf

Vo = -(V1 + V2 + .. + Vn)

5. Integrator Amplifier

    Integrator Amplifier is a configuration of OpAmp that integrates the inputs

Notable Formula:

Vo = -(1/RC) ∫Vidt
