10 Watt Audio Amplifier using Op-Amp and Power Transistors audio By Sourav Gupta Sep 24, 2018 4 Amplifiers are the backbone of Analog electronics. They are used vastly in the field of electronics industry. Amplifiers are used almost in all the audio related applications. Power amplifier is the part of sound electronics.

possible to make a suitable amplifier using an op-amp and a couple of external power transistors, but we went with a simpler solution, and chose a chip that was specifically designed as an audio driver, the LM386, shown in Figure 1-5.

AUDIO AMPLIFIERS 6.5 Transformer-Coupled Low-Impedance Microphone Preamps For any op amp, the best noise performance is attained when the characteristic noise resistance of the amplifier, Rn, is equal to the source resistance, Rs. Examples of microphone preamps that make use of this factor are discussed in this section. They
Audio Designs With Opamps
https://sound-au.com/dwopa.htm
There are few audio frequency designs today that do not use operational amplifiers (op-amps, or just 'opamps'). Over the years, the poor opamp has been much maligned, with mainly spurious claims about 'audibility', distortion, and other so-called defects.

The entire circuit of the microphone amplifier is built around operational amplifier 741. Op-amp 741 can be used in both inverting mode and non-inverting mode according to necessary. Here we use 741 in inverting mode because at inverting mode input impedance is low. A microphone is a transducer that changes sound energy into an electric signal.

Without trying to be snotty, have you tried the Internet? Put 741 amplifier schematic into any search engine and watch the circuits roll in. Separate from that, MrChips is right. For a basic audio amp, the 741 has too much baggage. A specialty audio amp chip is way less work, and the LM386 gets you 1-2 watts with very little effort.
