.The TDA7391 is an integrated circuit designed specifically for audio applications. It is a dual-channel high-power amplifier designed to amplify audio signals in sound systems. The TDA7391 is made of two monolithic integrated amplifiers, one for each channel. The amplifier is capable of delivering a maximum output power of 25 watts per channel. The TDA7391 is designed to be used with a wide range of audio signals, such as stereo music, computer and other multimedia audio sources.
The TDA7391 is designed with a low total harmonic distortion, leading to clear and precise sound output. The low distortion and low signal-to-noise ratio are important when dealing with high-quality audio. Additionally, the TDA7391 has excellent protection against thermal and overvoltage-damage, to ensure long-term reliability.
The working principle of the TDA7391 is based on the concept of negative feedback. The amplifier consists of two differential amplifiers which are connected in series. A voltage feedback signal is generated from the output of the amplifier, which is then fed back to the input of the amplifier. This feedback signal adjusts the output signal level in a closed-loop fashion, which allows the amplifier to accurately reproduce the original signal.
The TDA7391 is used in several types of audio systems, including car audio and home theater systems. Additionally, the TDA7391 is used in sound reinforcement systems, such as PA systems and DJ systems. The amplifier also finds use in portable audio systems, such as MP3 players and CD players.
In conclusion, the TDA7391 is a high-power audio amplifier designed specifically for audio applications. It features low distortion, low signal-to-noise levels, and excellent protection against thermal and overvoltage-damage. The amplifier is used in many types of audio systems, ranging from home theaters to sound reinforcement systems.
