Working Explanation

of Power OP-Amp Audio Amplifier

The High-Slew Rate Power OP Amp/Audio Amplifier uses an A759 IC as a buffer stage. This IC is specially designed for high-power audio applications and delivers excellent performance in terms of stability, gain, and distortion. It features a wide bandwidth of up to 200 kHz, ensuring that the amplifier can deliver exceptional performance even in high-frequency applications.

The output stage of this amplifier is designed to deliver up to 18 watts of power into an 8-ohms load. This is done by using a pair of 2N3055 transistors in a push-pull configuration. The push-pull configuration ensures that both halves of the waveform are amplified in equal amounts, resulting in an output signal that is highly balanced and free from distortion.

Furthermore, this amplifier is designed to deliver low distortion, producing only 0.2% distortion at 10 VRMS and 1 KHz into 8 ohms. This is achieved by using high-quality components and carefully designing the circuit layout to minimize the effects of thermal drift and noise.

Conclusion

In summary, the High Slew Rate Power OP Amp/Audio Amplifier using 2N3055, 2N3790 transistors, and A759 IC is an excellent choice for audiophiles who are looking for an amplifier that delivers high power, low distortion, and exceptional sound quality. By employing advanced technology and high-quality components, this amplifier is capable of delivering clear, accurate, and powerful sound, making it the perfect choice for anyone looking to upgrade their audio system’s performance. Whether you’re a music lover, a home theater enthusiast, or a professional sound engineer, this amplifier is sure to impress. So why wait?
