Audio amplifiers are an essential part of any sound system. They produce the sound you hear when you listen to music, movies and more. The TPA721DG4 is a high power audio amplifier designed for a variety of audio applications, ranging from mono and stereo public address systems to professional sound systems. This article will examine the application field and working principle of the TPA721DG4 audio amplifier.

Application Field of TPA721DG4

The TPA721DG4 is a high efficiency, high current, integrated audio amplifier and power output stage. It is ideal for a variety of professional and commercial audio applications, such as public address systems, Karaoke machines, professional speakers, and more. The TPA721DG4 is designed to deliver high-power output with low THD (Total Harmonic Distortion) and high power efficiency. It is a high-power, low-voltage audio amplifier, which makes it ideal for supplying dynamic sound in situations where high power and low heat are required.

Technical Specifications of TPA721DG4

The TPA721DG4 is a versatile audio amplifier, featuring a range of technical specifications that make it suitable for a variety of audio applications. These include:

• Power output: 40 W/ Channel @ 4 ohms
• Signal to noise: >= 95 dB
• Input impedance: 22K ohms
• Power supply: 9V ~ 18V DC
• Frequency response: 20Hz – 20kHz
• Operating temperature: 0 - 70 degrees Celsius

Working Principle of TPA721DG4

The working principle of the TPA721DG4 audio amplifier is based on the principle of negative feedback. When audio signals are input into the amplifier, the output signals are generated based on the input signals. This output is then fed back to the amplifier where it is compared against the input signals. The amplifier then adjusts its output to compensate for any differences between the input and the output. This process is known as negative feedback and it is used to ensure that the amplifiers output is consistent and undistorted.

The TPA721DG4 has a built-in protection circuit that enables it to provide reliable performance with minimal maintenance. This protection circuit monitors the amplifier\'s inputs, output, supply voltages and temperature to ensure that the amplifier remains within its specified range. If any of these parameters are pushed outside of their specified range, the amplifier will shut down to prevent any damage or distortion.

Conclusion

In conclusion, the TPA721DG4 is a high quality audio amplifier suitable for a variety of audio applications. It is designed to deliver high power output with low THD and high power efficiency. Its built-in protection circuit monitors its inputs, output, supply voltages and temperature to ensure that the amplifier remains within its specified range. The TPA721DG4 is an excellent choice for producing dynamic, quality sound in situations where high power and low heat are required.
