产品概述 返回TOP
CXAR41166为单声道、无破音、最大输出瓦数可调、无声噪声抑制、无需滤波器的3.3W D类音频功率放大器，不仅具有D类的高效率，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，使用者还可自行调整最大输出瓦数，不仅有效避免了大功率超载输出对喇叭的损坏，在无播音的情况下还会自动滤除噪声，同时带来舒适的听觉感受。CXAR41166采用9焊球WCSP封装。The CXAR41166 is a high efficiency, 3.3W mono class-D audio power amplifier with Non-Clip, Power Limit and Noise Gate. A low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplifying design. CXAR41166 having power limit interlock non-clip function, controls gain automatically and prevents output signals from being clipped at the supply voltage. In addition, this power limit function permits the maximum output to be arbitrarily specified to 100mW to 1000mW according to a speaker to use. The “Noise Gate” function removes the TDMA, DAC or white noise which comes in at no-signal state, by muting an output signal automatically when output level is low. With this function, the very low noise characteristics can be realized. Furthermore, CXAR41166also integrate overcurrent and overtemperature protection functions, DC output protection function, under-voltage malfunction prevention function, as well as EMI noise and the pop noise reduction functions. The CXAR41166is available in space-saving WCSP package.
