   产品概述 返回TOPr0C嘉泰姆

The CXAR41184 is a dual audio power amplifier capable of delivering 158mW per channel of continuous average power with typically 0.1% distortion (THD+N) 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 amplifier has minimum of external components and can operate from a single 2.5V to 5.5V power supply.r0C嘉泰姆

CXAR41184 features an externally controlled, active-low, micro-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. CXAR41184 does not require bootstrap capacitors or snubber networks. It is optimally suited for low power portable systems.r0C嘉泰姆

For maximum flexibility, the CXAR41184 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor).r0C嘉泰姆

The CXAR41184 is available in Green MSOP-8 package. It operates over an ambient temperature range of -40℃</span> to +85℃</span>.r0C嘉泰姆
