CXAR41199是一个双桥连接的音频功率放大器，当连接到5V电源时，将2.1W输出到4Ω负载，或2.5W输出到3Ω负载，通常为1%THD+N。此外，耳机输入引脚允许放大器在驾驶立体声耳机时以单端模式工作。
为了简化音频系统设计，CXAR41199将双桥扬声器放大器和立体声耳机放大器结合在一个芯片上。
CXAR41199具有低功耗关机模式和热关机保护。它还利用电路来减少设备开启时的“弹出/点击”。
CXAR41199有绿色TSSOP-20（外露衬垫）、TQFN-3×3-20L、TSSOP-16（外露衬垫）、SOIC-16和DIP-16包装。它在-40℃到+85℃的环境温度范围内工作。

产品概述 返回TOP
The CXAR41199 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.
To simplify audio system design, the CXAR41199 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
The CXAR41199 features a low power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “pop/click” during device turn-on.
The CXAR41199 is available in Green TSSOP-20 (Exposed Pad), TQFN-3×3-20L, TSSOP-16 (Exposed Pad), SOIC-16 and DIP-16 packages. It operates over an ambient temperature range of -40℃ to +85℃.
