产品简介

CXAR41102是一款立体声、高效率、无滤波器的D级音频放大器，采用TQFN3x3-16针封装。内部增益设置可以最小化外部元件数量并节省PCB空间。对于灵活的应用，可以通过增益控制管脚将增益设置为6dB或12dB。高PSRR和差分架构提高了对噪声和RF整流的免疫力。除了这些特点，短的启动时间和小的封装尺寸使CXAR41102成为蜂窝手机、PDA和笔记本电脑的理想选择。CXAR41102适用于电池供电，因为它的工作电压在2.4V到5V之间，并且具有非常低的关机电流。与传统的D类音频放大器相比，无滤波器结构消除了输出滤波器，减少了外部元件的数量。CXAR41102还集成了防弹出电路，可减少通电/断电或关机启用过程中的弹出声和咔哒声。CXAR41102能够在5v下驱动2.8w或在2.4v下驱动570mw到4W扬声器。此外，它还提供热保护和过电流保护。

   产品概述 返回TOP

The CXAR41102 is a stereo, high efficiency, filter-free ClassD audio amplifier available in a TQFN3x3-16 pins package. The internal gain setting can minimize the external component count and save the PCB space. For the flexible application, the gain can be set to 6dB or 12dB by GAIN control pin. High PSRR and differential architecture provide increase immunity to noise and RF rectification. In addition to these features, short start-up time and small package size make the CXAR41102 an ideal choice for cellular handsets, PDA, and notebook PCs. The CXAR41102 is suitable for battery power appication because its operating voltage is from 2.4V to 5V and has very low shutdown current. The filter-free architecture eliminates the output filter compared to the traditional Class-D audio amplifier, and reduces the external component counts. The CXAR41102 also integrates the de-pop circuitry that reduces the pops and click noises during power on/ off or shutdown enable process. The CXAR41102 is capable of driving 2.8 W at 5 V or 570 mW at 2.4 V into 4W speaker. In addition, it provides thermal and over-current protections.
