Class-AB Audio Power Amplifiers - STMicroelectronics
https://www.st.com/en/audio-ics/class-ab-audio-power-amplifiers.html
The STA540 contains four single-ended, class-AB audio amplifiers assembled in a Multiwatt15 package. These amplifiers are used for high-quality sound applications. Each amplifier has integrated short-circuit and thermal protection and diagnostic functions. Two amplifiers can be paired up for applications requiring high power output. Products
Class AB Audio Amplifier - HACK A WEEK
http://hackaweek.com/hacks/class-ab-audio-amplifier/
This week we’ll take a look at another type of audio amplifier, the class AB amp. As we saw in Hack #19 the class A amp has a transistor that is biased with a voltage that makes it essentially stay turned on all the time. This single transistor handles the entire waveform both positive and negative. The class B amplifier uses two transistors.

I am required to design a class AB audio amplifier to deliver 10W to an 8Ω speaker as shown, but I don't know where to start. The bandwidth is to cover the range from 20Hz to 18kHz. Input voltage is 500mV rms. Image source: Electronics Tutorials - Class AB Amplifier Driver Stage. This is what I have done so far.

It shows a class AB output stage (Tr2 and Tr3) and a class A audio driver (voltage amplifier) Trl. The circuit features both AC negative feedback to reduce distortion and noise, and widen bandwidth, as well as DC negative feedback to stabilise the DC biasing.
Class AB Output Stage - University of Pennsylvania
https://www.seas.upenn.edu/~ese319/Lecture_Notes/Lec_22_ClassAB_Amplifier_12.pdf
The Class AB circuit, over most of its input signal range, operates as if either the Q N or Q P transistor is conducting and the Q P or Q N transistor is cut off. For small values of v I both Q N and Q P conduct, and as v I is increased or decreased, the conduction of Q …
