The op-amp output is connected to the center of diode-resistor biasing circuitry, and this signal manipulate the biasing point. At idle condition, when there is no signal in the input, the output should be bet at Vcc/2.

Audio Op Amps - It's The Loop Gain You Seek, Not The ...

https://sparkoslabs.com/discrete-op-amps/audio-op-amps-gain-seek-bandwidth/

When choosing an audio grade op amp, some opt for high loop gain devices as it is well known that high loop gain makes for a more precise amplifier and lower THD specifications. Others decry the use of high gain devices, claiming the high gain …

Understanding Op Amp Noise in Audio Circuits

https://www.ti.com/lit/pdf/sboa345

2 Operational Amplifier Voltage Noise. An operational amplifier has a voltage noise and current noise source. The magnitude of the noise sources inside the amplifier is given in the amplifier’s data sheet. When considering the voltage noise of an amplifier, it is important to realize the architecture of the amplifier.

Opamp vs audio amplifier?? | All About Circuits

May 7, 2017. #3. To start with. Audio is defined as frequencies from 20 Hz to 20 kHz. So. If you have op amp that only goes to 10 kHz... you safely say that it is not audio amplifier. Also. Since you don't need hundredth of MHz, those op amps, while nice, are not needed. 1.760 kHz seems too low to me to be audio.

Amplifiers are used almost in all the audio related applications. Power amplifier is the part of sound electronics. It is designed to maximize the magnitude of the power of given input signal. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load.

CHAPTER 1: THE OP AMP

https://www.analog.com/media/en/training-seminars/design-handbooks/Basic-Linear-Design/Chapter1.pdf

The name “op amp” is the standard abbreviation for operational amplifier. This name comes from the early days of amplifier design, when the op amp was used in analog computers. (Yes, the first computers were analog in nature, rather than digital). When the basic amplifier was used with a few external components, various mathematical

Audio Designs With Opamps

https://sound-au.com/dwopa.htm

The operational amplifier was first used in the 1930's as the basis of analogue computers, and much development took place to design accurate gun aiming systems during the Second World War. Since integrated circuits were unknown at the time (this was before the invention of the transistor), the earliest versions were made using valves.
