         CXAR41167 是一款高效率，每个通道具有2.5W功率输出的双声道D类音频放大器，它用一种低噪声filterless PWM的架构，无需输出滤波器，实际应用上只需使用两个外部组件。电源电压为5V时，CXAR41167能在输出负载为4Ω的扬声器上，单一通道可以输送出2.5W/10% 的输出功率及失真度。CXAR41167具有两个独立的关断(Shutdown)控制信号，可以单独关闭左声道或右声道。利用G0与G1两个接脚，可以选择增益为6、12、18或是24dB。高电源拒斥比(PSRR)以及全差动设计可以有效抑制噪声以及射频(RF)干扰。CXAR41167采用WCSP以及TQFN封装，适合行动电话或是可携式行动通讯系统使用。The CXAR41167 is a high efficiency, 2.5W/channel stereo class-D audio power amplifier. A low noise, filterless PWM architecture eliminates the output filter, requiring only two external components for operation. Operating from a single 5V supply, CXAR41167 is capable of delivering 2.5W/ channel of continuous output power to a 4Ω load with 10% THD+N. The CXAR41167 features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain select pins. High PSRR and differential architecture provide increased immunity to noise and RF rectification. The CXAR41167 is available in space-saving WCSP and TQFN packages, is an idea choice for mobile phones and other portable communication devices.
