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 ...

10 Watt Audio Amplifier Circuit Diagram and Explanation. The schematic for 10 watt amplifier is pretty simple, the LF351 amplifies the signal voltage and two Power Transistors provide the necessary power amplification. The power is directly taken from the power supply and provided to the 8 Ohms Loud Speaker via two transistors.
Audio Op Amps - It's The Loop Gain You Seek, Not The ...

Introduction: Numerous opinions and preferences exist regarding op amp selection for hi-fi audio circuits.The question we attempt to answer is "Which op amp is the best for audio applications?" We go on Digikey, look up the AD's, LT's, LM's and NE's, and rapidly find our eyes glazing over from specification overload.
Notes on Audio Op-Amps - Tangentsoft
https://tangentsoft.net/audio/opamps.html
We can eliminate power op-amps, super-high-speed op-amps, high-voltage op-amps, low-frequency op-amps, and low-spec general-purpose op-amps. Audio requires a fairly high slew rate to maintain low distortion, flat frequency response from 20 Hz to 20,000 Hz, and decent output current if the chip is to drive headphones directly.
Opamp vs audio amplifier?? | All About Circuits
https://forum.allaboutcircuits.com/threads/opamp-vs-audio-amplifier.135094/
shteii01 said: 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.
