CXAR41260是一个双桥连接的音频功率放大器，当连接到5V电源时，将以小于1.0%THD+N的功率向4Ω负载（注1）输出2.2W，或向3Ω负载（注2）输出2.5W。此外，耳机输入引脚允许放大器在单端模式下工作以驱动立体声耳机。Boomer音频功率放大器专门设计用于提供来自表面安装包的高质量输出功率，同时需要很少的外部组件，为了简化音频系统设计，它将双桥扬声器放大器和立体声耳机放大器组合在一个芯片上。CXAR41260具有外部控制、低功耗关机模式、立体声耳机放大器模式和热关机保护。它还利用电路来减少设备开启时的“咔嚓声和砰砰声”。

产品概述 返回TOP
The CXAR41260 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load(Note 1) or 2.5W to a 3Ω load(Note 2) with less than 1.0% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode to drive stereo headphones. Boomer audio power amplifiers were designed specifically to provide high quality output power from a surface mount package while requiring few external components,to simplify audio system design, it combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip. The CXAR41260 features an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on.
