TDA7491HV13TR Application Field and Working Principle
Audio power amplifiers are the most common application of linear amplifiers. They are used to amplify audio signals which can be broadcasted on a loudspeaker, enabling people to hear and enjoy the music that is playing. The TDA7491HV13TR is a four-channel stereo audio power amplifier IC from NXP. It has two operational amplifiers, a Class AB output stage plus protection, and a current-closed loop control. This makes it ideal for use in compact stereo power amplifiers, sound bars and active speakers.Features of the TDA7491HV13TR
The TDA7491HV13TR has a wide range of features that make it ideal for audio power amplifier applications. It has two independent operational amplifiers, allowing it to independently control the current of two different channels. This provides users with flexibility and versatility, allowing them to achieve different sounds and effects. It also has a current-closed loop control and protection, which helps to protect and extend the life of the device. Finally, the TDA7491HV13TR has a Class AB output stage, which means that it can produce high output power without distortion.Working Principle
The TDA7491HV13TR follows the traditional linear amplifier design, which is based on the concept of voltage amplification. This involves taking a low-voltage input signal, amplifying it, and then applying it to the output stage. The output stage can then be used to either raise or lower the amplitude of the signal, depending on the desired output. The TDA7491HV13TR uses a differential input stage, which is designed to amplify signals with minimal distortion. It also uses a Class AB output stage, which is designed to provide more power and lower distortion. The TDA7491HV13TR also incorporates a current-closed loop control and protection, which helps to protect the device from short-circuiting and overloading.Conclusion
The TDA7491HV13TR is a powerful and versatile four-channel stereo audio power amplifier IC from NXP. It has two independent operational amplifiers, a current-closed loop control and protection, and a Class AB output stage. This makes it ideal for use in compact stereo power amplifiers, sound bars and active speakers. It follows the traditional linear amplifier design, which is based on the concept of voltage amplification, and incorporates features such as differential input stage and current-closed loop control and protection. Overall, the TDA7491HV13TR is an ideal choice for those looking for a powerful and reliable audio power amplifier with a wide range of features.The specific data is subject to PDF, and the above content is for reference
