Application Fields

The TDA8920BTH/N2,118 amplifier is an excellent choice for high power audio applications. It is particularly suited for use in high-end home theater systems, as well as for applications requiring high power such as subwoofer systems, powered speaker systems, PA systems and more. Its low noise efficiency, low distortion, high frequency stability and high-fidelity audio performance make it a great choice for both professionals and home theater users, alike. It can also be used in a variety of other audio applications, including amplifying high-end music playback systems, car audio systems and much more.

Working Principle

The TDA8920BTH/N2,118 amplifier is a class AB amplifier operating in linear mode. This means that the amplifier works by amplifying a single input signal linearly, rather than compressing it, which is what a class A amplifier does. This enables the amplifier to provide more efficient power output by reducing the total number of transistors used, as well as decreasing the amount of distortion produced. The amplifier is designed with transistors connected to the same power supply and dedicated power supplies. This configuration allows for amplification of both the voltage and current of the single input signal, increasing power output and resulting in higher quality audio output.

In addition to its linear operating mode, the TDA8920BTH/N2,118 amplifier is also designed to have a low signal-to-noise ratio (SNR). This is achieved by providing the amplifier with a high input impedance, which allows it to differentiate between the signal and the background noise. The high-impedance input reduces the amount of background noise, resulting in higher quality audio output.

The amplifier also includes two separate volume controls, allowing for greater control of the signal. These controls are adjustable and can be adjusted to punish some frequencies more than others, resulting in more accurate and realistic audio output. Additionally, the amplifier has very low distortion performance, ensuring high-quality sound output. Moreover, the amplifier is also highly efficient, resulting in reduced energy consumption.

Conclusion

The TDA8920BTH/N2,118 amplifier is an excellent choice for high performance audio applications. It is a high power amplifier capable of delivering up to 120 W of audio output power. The linear operating mode and high input impedance results in low distortion, low signal-to-noise ratio, high efficiency and excellent sound quality. It is suitable for use in high-end home theater systems, subwoofer systems, powered speaker systems and a variety of other audio applications.
