Dual Channel Audio Power Amplifier Based on TDA2822
Abstract:In recent years, with the development of electronics industry technology and electronic and electrical industries, the ability to manufacture electronic components has become more and more important. Due to the improvement of production technology and the improvement of processing technology, the development of integrated circuit technology is also fast. Under the background of this research, this dissertation uses Altium Designer analog simulation circuit system to design a dual-channel audio power amplifier based on TDA2822 integrated circuit. The research goal is to realize the power of two-channel audio signal with the voltage amplification factor as the parameter standard. Zoom in. This circuit has low cost, good sound quality, wide voltage range, and simple and clear. This design can be applied not only to home mini speakers, but also to commercial sound systems. It can also be used as experimental teaching and has a wide range of applications.
