是一款桥接捆绑负载（BTL）音频功率放大器，专为需要内部扬声器操作的低压应用开发。CXAR4183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 8W负载提供1.1W的连续功率。尽管该设备的特点是20kHz，但它的操作是为窄带应用程序的UCH作为有线通信而优化的。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。CXAR4183在8针SOP中提供。

产品概述 返回TOP
The CXAR4183 is a bridged-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers operation is required. Operating with a 5V supply, the CXAR4183 can deliver 1.1W of continuous power into a BTL 8W load at 10% THD+N throughout voice band frequencies. Although this device is characterized out to 20kHz, its operation is optimized for narrow band appl i c ati ons s uc h as wireles s 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 CXAR4183 is available in8-pin SOP.
