The TDA7379 chip, which is a 4-channel class AB power amplifier, has gained widespread popularity in many fields, especially in linear audio applications. Although it belongs to linear amplifiers, its features and capabilities are more focused towards audio applications than any other application.

Obviously the primary purpose of the amplifier is to increase the power of the original signal, a consequence of this process, however, is that there will be some noise added to the signal due to the amplification process. For audio applications, this noise is extremely important and is often referred to as \'crosstalk\' or \'distortion\'. In order to reduce the amount of noise in the final signal output, the TDA7379 is designed with a large number of frequency-dependent components in order to minimise any potential distortion, thus making it ideal for audio applications.

The TDA7379 works on the principle of class AB amplification which allows the amplifier to produce high levels of power with relatively low levels of distortion and heat generation. This is because the transistors are used in pairs, with each transistor being capable of driving a pair of audio channels independently. This means that the amplifier can produce a much higher output power without causing any kind of distortion or heat related issues.

The amplifier is also designed to operate at any frequency between 10Hz and 20KHz, meaning that it can be used in a wide range of audio applications. Additionally, the amplifier is designed to operate at a voltage range of 4 to 6 volts, which makes it ideal for use in portable applications. The power output of the amplifier is also adjustable in increments of 1dB, making it easy to adjust for different environments.

In terms of physical size, the TDA7379 is relatively small, measuring just 10mm x 10mm x 8mm, which means that it can be used in a variety of applications where space is limited. The amplifier is also capable of operating in temperatures ranging from -20 to +85 degrees Celsius, which makes it suitable for use in a multitude of environments.

Overall, the TDA7379 is an outstanding choice for linear audio applications due to its excellent power output, low level of distortion, and its ability to handle a wide range of frequencies and voltages. Furthermore, its small size makes it ideal for use in a variety of applications where space is at a premium. While other amplifiers may have better features in certain areas, the TDA7379 is a comprehensive package that provides users with an effective audio amplifier solution.
