     CXAR41169单声道、无破音、低EMI、2.8W、无需滤波器的D类音频功率放大器不仅具有D类的84%高效率，还有独特的无破音功能，可以通过检测输出的破音失真，自动调整系统增益，不仅有效避免了大功率超载输出对喇叭的损坏，同时带来舒适的听觉感受。CXAR41169采用9焊球WCSP和8 PIN TDFN封装。The CXAR41169 is a high efficiency, 2.8W mono class-D audio power amplifier with non-clip. A low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplifying design. Operating in a single 5V supply, CXAR41169 is capable of driving 4Ω speaker load at a continuous average output of 2.8W/10% THD+N or 2.2W/1% THD+N. The CXAR41169 has high efficiency with speaker load compared to a typical class AB amplifier. With a 3.6V supply driving an 8Ω speaker , the efficiency for a 400mW power level is 84%. CXAR41169 feature non-clip output control function which detects output signal clip due to the over level input signal and suppress the output signal clip automatically. Also the non-clip output control function can adapt the output clip cause by power supply voltage down with battery. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the CXAR41169 The CXAR41169is available in space-saving WCSP and TDFN-8 packages.
