Question

Advantages and disadvantages of inverting amplifier

Answer 1

Answer:

The non inverting amplifier can have a direct input (no input resistor) and low value feedback resistors to reduce noise to a minimum and enjoy high input impedance. Of course if you need inversion and noise is not an issue then it is fine.

Answer 2

Advantages:

• It avoids the inverting relation of an OP Amp in audio and instrumentation because it has lower input impedance and more distortion attributable to the input resistor.
• It has low-value feedback resistors to decrease distortion and get high input impedance.

Disadvantages:

• The real drawback of the inverting amplifier is the input impedance of the amplifier, which is equivalent to R1.
• The signal is reversed, which can be very distracting though with that we cannot invert it again.
