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 …
operational amplifier - Which op-amp for audio ...

Op-amps have a gain-bandwidth product (GBW) which indicates that the bandwidth depends on the amplification; a higher gain (amplification) results in a lower bandwidth. GBW is closely related to slew-rate, and you want to have a much wider bandwidth than the 20Hz-20kHz of audio to get high slew-rate values.

Audio Designs With Opamps

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.

The input of the opamp should be at half the supply voltage which is ground with a dual polarity supply. If you use a single polarity supply then use two resistors and a filter capacitor to make a voltage divider that provides half the supply voltage. The output will also be at half the supply voltage so a coupling capacitor must feed the speaker.

The same is true about the LME49722, and others (LM6172 above all). The LM4562 is decent but the LME49723 sounds better. The OPA132UA is the best FET opamp that I know of. I still want to try (in the DAC I mentioned) the THS4051 and the OPA1611. The LT1028CS8 is what I use now and it's excellent..

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.

For line-in, it doesn't matter that much. LM4562 has got pretty good specs as for a bipolar input op-amp but it sounds mediocre to my ears. AD823 is tolerable but it sounds better when supplied from higher voltages. Finally, don't look at the slew rate, all of them have got it sufficient for audio.

An Operational Amplifier, or op-amp for short, is fundamentally a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. These feedback components determine the resulting function or “operation” of the Amplifier and by virtue of the different feedback configurations …
