Audio special purpose has many applications, one of which is TDA7721. This article will focus on the application fields and working principle of TDA7721.

TDA7721 is a 4-band graphic equalizer integrated audio processor with a single supply voltage. It is a low cost, high performance IC that offers a wide range of functionality. TDA7721 is a versatile IC that is suitable for a variety of applications, including car audio systems, graphic equalizers, and karaoke systems. It offers an ease of application and is suitable for high volume applications.

TDA7721 has a wide range of application fields. It can be used in car audio systems for sound equalization and analysis. It can also be used for optimizing the sound in karaoke systems. It can also be used in other consumer audio electronics such as amplifiers and home theater systems.

The working principle of TDA7721 is relatively straight forward. When the power supply is on, a signal is sent to the IC. This signal is processed by the IC and sent to the output via a four-band graphic equalizer. The graphic equalizer is designed to adjust the sound according to user preferences. The sound can be made richer or thinner, brighter or darker. This is the main function of the TDA7721.

Once the sound is adjusted, it is sent to the output. TDA7721 also allows for adjusting the volume and using a bass boost circuit to enhance the low frequencies. This is done by adjusting a frequency slope, which can be adjusted in two different ways: active frequency slope and passive frequency slope.

In conclusion, TDA7721 is a versatile IC that can be used for a variety of audio applications. It has numerous application fields, including car audio systems and karaoke systems. Its working principle is relatively straight forward and it offers a wide range of functionality. Therefore, it is ideal for high-volume applications.
