What is Operational Amplifier(OP-AMP) ?

What is OP-AMP

An OP-AMP is a circuit that can perform such mathematical operations as addition, subtraction, integration and differentiation.

Characteristics of Ideal OP-AMP

1. Infinite Gain

2. Infinite Bandwidth

3. Infinite Input Impedance

4. Zero Output Impedance

5. Zero Input Current

6. Zero Input Voltage Offset

Inverting Amplifier(/Negative Scalar)

Incase of inverting amplifier, the non-inverting terminal is grounded, the resistor R1 connects the input signal V1 to the inverting input and feedback resistor Rf is connected from the output to the inverting input
