   产品概述 返回TOPOYg嘉泰姆

      CXAR41175是一款20W，4通道半桥式驱动的高效数字音频功率放大器。经由外部时钟信号驱动。I2S串行数据输入接口允许同时处理两个分离声道，并且可以无缝整合到大多数的数字音频处理器。器件可以接收一个很宽范围的输入数据和数据速率。内置双向I2C接口可以接受主机的各种指令改变内部寄存器状态。CXAR41175提供短路保护和过热保护，以避免芯片的损毁。CXAR41175采用48-pin TQFP封装。The CXAR41175 is a 20-W, digital audio power amplifier with 4 half-bridged power drivers. The CXAR41175 is a slave device that all clocks are provided by the external sources. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors. A bidirectional I2C interface allows reading or writing to change the internal register status. The CXAR41175 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The CXAR41175 is available in thermally efficient 48-pin TQFP package.
