摘要
介绍D类音频放大器MAX9736A/B在立体声MP3坞站(docking station)中的应用。MAX9736A/B的2.1声道演示盒是一个完整的扬声器坞站。该系统设计采用两片MAX9736驱动由两个2英寸卫星扬声器和一个5英寸重低音扬声器构成的三声道扬声器系统。详细介绍该系统设计的硬件电路和扬声器。该系统设计具有有源均衡、电源监控以及重低音扬声器的动态均衡功能,用于便携式音频播放器。
This paper demonstrates the use of the MAX9736 class D audio amplifier in a stereo audio MP3 docking station application. The MAX9736 2.1 demo box is a complete powered speaker dock. The system design uses two MAX9736 ICs to drive a 3-channel speaker system consisting of two 2in satellite speakers and one 5in subwoofer. The paper introduces the system design hardware circuit and speaker in detail.The system design features active equalization, power-supply monitoring,and dynamic equalization for the subwoofer, and is intended to be used with a portable audio player.
