   产品概述 返回TOPR19嘉泰姆

The CXAR41119 is a digital input, stereo, high efficiency, Class-D audio amplifier available in a TQFP7x7-48P package. The CXAR41119 accepts the digital serial audio data and using the digital audio processor to convert the audio data becomes the stereo Class-D output speaker amplifier. This provides the seamless integration between the codec and the speaker amplifier. The CXAR41119 is a slave device receiving clocks from external source, and the Class-D’s PWM switching frequency is 352.8kHz for the sampling rate 44.1kHz or 384 kHz for sampling 48kHz, depend on the input signal’s sampling rate.
