产品简介

CXAR41114 CXAR41114A是一种桥接捆绑负载（BTL）音频功率放大器，专门为内置扬声器的低压应用开发。CXAR41114 CXAR41114a在5V电源下工作，可在整个声带频率中以10%THD+N的频率向BTL 3W负载提供3.3W的连续功率。虽然该设备的特点是20千赫，但其操作是优化的窄带应用，如无线通信。在大多数应用中，BTL配置消除了对输出端外部耦合电容的需求，这对于小型电池供电设备尤为重要。该设备的特点是功率敏感的应用关闭模式与特殊的depop电路，以消除扬声器噪音时退出关闭模式。CXAR41114 CXAR41114A有SOP-8、SOP-8P或MSOP-8P。

   产品概述 返回TOP

The CXAR41114/A is a bridged-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers. Operating with a 5V supply, the CXAR41114/A can deliver 3.3W of continuous power into a BTL 3W load at 10% THD+N throughout voice band frequencies. Although this device is characterized out to 20kHz, its operation is optimized for narrow band applications such as wireless communications. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications, which is particularly important for small battery-powered equipment. This device features a shutdown mode for power sensitive applications with special depop circuitry to eliminate speaker noise when exiting shutdown mode. The CXAR41114/A are available in a SOP-8, SOP-8P or MSOP-8P.
