STA540 power amplifier. 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 ...
Class AB Audio Amplifier | HACK A WEEK

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.

Then the amplifier classes are always defined as follows: Class A: – The amplifiers single output transistor conducts for the full 360 o of the cycle of the input waveform. Class B: – The amplifiers two output transistors only conduct for one-half, that is, 180 o of the input waveform. Class AB: – The amplifiers two output transistors conduct somewhere between 180 o and 360 o of the ...

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.
