This is the Clipping Amplifier Circuit using LM741 (popular op-amp IC. It is a basic clipping amplifier. If the input is sine wave to distorted square wave type waveform. Vout = -Vin (R2/R1) But the Vout not up to Vz+0.7V The D1 and D2 are a Zener diode. If we use 6V values, have already the output voltage not exceed +/- 6.7V.

Circuit description of microphone amplifier using 741 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.

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.

The op-amp IC 741 is a DC-coupled, high gain differential amplifier with external negative feedback. IC 741 is characterized by the almost infinite open-loop gain (100,000), almost infinite input impedance (2MΩ), and almost zero output impedance (75Ω). Other Op-Amp circuits include audio amplifier LM358, comparator IC LM324, and other dual-channel IC.

Universal Preamplifier using 741 This is a mono preamplifier circuit. Which it can use with various inputs. For example, microphone, tuner, CD and AUX. In the circuit above, IC741 is set into inverting amplifier mode. When a signal flows to AF in through C1 and R1 to pin 2 of IC1. Then, the signal goes out of pin 6. R4 acts as feedback resistors.

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.

Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.
Audio Designs With Opamps
https://sound-au.com/dwopa.htm
Designing With Opamps - Part 1. 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. There are even people who will compare the bass ...
