     CXAR41178为一款非立体声的G类功率放大器，由内部集成的负电荷泵作为电源供电。当电荷泵输出电压大于5V时，可提供高达500mA的峰值输出电流，从而保证14VP-P的输出。CXAR41178通过G类输出级提供良好的性能，相较于AB类元件具有更高的效率，不存在与D类放大器相关的EMI干扰。CXAR41178针对陶瓷型/压电扬声器提供高电压输出摆幅的理想设计。该设备利用全差动输入和和全差动输出，内置shutdown控制电路，综合Click和pop噪声抑制电路和软启动电路。CXAR41178采用TQFN-28 封装。The CXAR41178 is a mono Class G power amplifier with an integrated inverting charge-pump power supply. The charge pump can supply up to 500mA of peak out-put current over at 5V, guaranteeing an output of 14VP-P. The CXAR41178 offers good performance through the class G output stage, which provides efficiency levels greater than Class AB devices without the EMI penalties commonly associated with Class D amplifiers. The CXAR41178 is ideally designed to deliver the high output voltage swing for ceramic/piezoelectric speakers. The device utilizes fully differential inputs and outputs, comprehensive click-and-pop suppression, shutdown control, and soft-start circuitry. The ECXAR41178is available in 28-pin TQFN (4mm×4mm) package.
