Can you use an op amp as an audio amplifier?
Equivalent Input Noise and Typical Harmonic Distortion Op amps do not only amplify your source signal, they also add harmonics and noise. For audio applications it is essential to choose an op amp with low noise and distortion.
What is op amp audio amplifier?
An operational amplifier (often op amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.
How does audio amplifier circuit work?
The function of audio power amplifier is to amplify the input signal from the audio source, and then drive it to the speaker. The audio sources are various: for example, microphone, record player, CD player etc. For the low input signal, the output power is low, and the power amplifier cannot use full capacity.
What is the difference between op amp and amplifier?
An op-amp has two input terminals, two power inputs and one output terminal. Op-amp is a differential amplifier, which means the amplifier amplifies the voltage difference between the inverting input and the non-inverting input. This allows the op-amp to operate on common mode signal rejection.

What is the purpose of audio amplifier?
The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion.
Why do we need an op amp?
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
