MAX97220CETE+ Application Field and Working Principle

Linear amplifiers are widely used in audio applications to increase the distortion performance and efficiency of audio signals. In order to meet the increasing demand for high performance audio systems, Texas Instruments has released the MAX97220CETE+ quad-channel high-efficiency audio amplifier. This device is designed to deliver excellent audio performance while maximizing system power efficiency. This article will discuss the MAX97220CETE+ application field and working principle, in order to explain its advantages over other similar devices.

Application Field of MAX97220CETE+

MAX97220CETE+ is ideally suited for applications such as digital audio amplifiers, speakers and soundbars, automotive audio systems, and gaming headsets. In these applications, the MAX97220CETE+ provides four 120-W peak output ports, which means it can provide up to 480-W peak-to-battery audio power. Moreover, it has a very low EMI and low total harmonic distortion of 0.005%. This low distorition also helps to reduce noise and hiss, making it especially suitable for high precision audio applications.

Working Principle of MAX97220CETE+

The MAX97220CETE+ uses a Class-D switching architecture to amplify audio signals. When an audio signal is received from a source, it will be amplified by the MAX97220CETE+ before being sent to the load. The advantage of the Class-D architecture is that it allows for higher efficiency than Class-AB or Class-B architectures. The efficiency of the MAX97220CETE+ is further increased by its multi-phase approach and its low quiescent current. The multiple phase approach helps to minimize the power dissipated by switching transistors, while the low quiescent current allows for improved efficiency in light-load conditions.

Conclusion

The MAX97220CETE+ is an ideal audio amplifier choice for audio and automotive applications. With the combination of its excellent audio performance and its high efficiency, it is the perfect choice for demanding audio applications. Its low distortion, low EMI and low quiescent current, coupled with its Class-D switching architecture, ensure that the MAX97220CETE+ is an excellent choice for high precision audio applications.
