   产品概述 返回TOPHWM嘉泰姆

The CXAR41188 is a dual audio power amplifier capable of delivering 145mW per channel of continuous average power with less than 0.1% distortion（</span>THD）</span>when it drives a 16Ω speaker from a 5.0V power supply. It is designed to maximize audio performance in portable applications such as mobile phone. The portable application requires audio power amplifierhas minimum of external components and can operate from a single 2.5V to 5.5V power supply.HWM嘉泰姆

CXAR41188 features an externally controlled, active-low, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.HWM嘉泰姆

CXAR41188 does not require bootstrap capacitors or snubber networks. It is optimally suited for low-power portable systems.HWM嘉泰姆

For maximum flexibility, the CXAR41188 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor).HWM嘉泰姆

The CXAR41188 is available in Green TDFN-2×2-8L package. It operates over an ambient temperature range of -40℃</span> to +85℃</span>.HWM嘉泰姆
