Audio Designs With Opamps
https://sound-au.com/dwopa.htm
There are faster opamps, opamps with better DC offset performance and others with lower distortion, but the NE5532 dual opamp (and the single version, the NE5534) are already more than capable of handling more than 99% of all common audio requirements.

By Douglas Self 05.25.2011 0. Audio design has for many years relied on a very small number of op-amp types; the TL072 and the 5532 dominated the audio small-signal scene for many years. The TL072, with its JFET inputs, was used wherever its negligible input bias currents and low cost were important. For a long time the 5534/5532 was much more …

the op amp’s place in the world of analog electronics. Chapter 2 reviews some basic phys-ics and develops the fundamental circuit equations that are used throughout the book. Similar equations have been developed in other books, but the presentation here empha-sizes material required for speedy op amp design. The ideal op amp equations are devel-

Figure 2. Schematic Diagram of Small Audio Power Amplifier Circuit Using Op-Amp and Two Transistors. Let’s imagine the op-amp is omitted, then the base-to-base voltage is the voltage between R4 and R5 which is dropped by two diodes D1-D2. This voltage is slightly higher than base-to-base bias requirement to produce small leakage current when ...
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 …

speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

Playing at Discrete Op-Amp Design. The OP and at least one participant of this cool thread asked for details on some of my discrete op-amp designs. So a little context, these were designed for my tape amplifier project. There are 4 variants; one is yet untested, and I will share the one I am currently using in the front end in this post.
