A Variable Audio Frequency Oscillator Using Op-amp 741
https://bestengineeringprojects.com/a-variable-audio-frequency-oscillator-using-op-amp-741/
Circuit Description of A Variable Audio Frequency Oscillator Using Op-amp 741. The circuit of variable audio frequency oscillator using op-amp 741 is mainly a Wein Bridge oscillator whose frequency is varied using the gang condenser. While using the IC 1 741 (operational amplifier), the use of split power supply has been avoided by using capacitors C 1 …
LC Oscillator Circuits using Transistors and Op Amp

There are more versatile op-amp models commonly available for the beginner. I recommend the LM324 for DC and low-frequency AC circuits, and the TL082 for AC projects involving audio or higher frequencies. As usual, avoid very high and very low resistor values, to avoid measurement errors caused by meter “loading”.

The op-amp based oscillator, which produces a sinusoidal voltage signal at the output with the help of an inverting amplifier and a feedback network is known as a RC phase shift oscillator. This feedback network consists of three cascaded RC sections. The circuit diagram of a RC phase shift oscillator is shown in the following figure −
Audio Designs With Opamps
https://sound-au.com/dwopa.htm
When an opamp is operated in its linear mode (which is most of the time for audio and most other amplification circuits), the negative feedback circuit will cause a voltage to appear on the inverting input (-in) that is ( almost) exactly equal to that present on the non-inverting input (+in).

The Wien bridge oscillator is one that has been around for many years, and it finds applications in many areas as an audio oscillator, either using discrete electronic components, or using operational amplifiers. As op amps are such easy electronic components to use, providing near perfect operation, they are widely used in circuits like these.
