CXAR41112

CXAR41112是一款立体声、高效率的D级音频放大器,有TSSOP-28P和QFN4x4-28B针两种封装。与传统的AB类功率放大器相比,D类功率放大器具有更高的效率。无滤波器D类结构消除了外部低通滤波器。内部增益设置可以最小化外部组件计数,对于灵活应用,增益可以通过增益控制管脚(GAIN0和GAIN1)设置为4步20、26、32、36dB。自动增益控制(AGC)功能可防止扬声器超出其额定功率,但保持可接受的性能。D类功率放大器的集成化是高效率、低BOM成本的最佳解决方案。工作电压从4.5V到26V,CXAR41112功率放大器能够在VDD=16V的电压下驱动15W到8W扬声器,并提供热保护和过电流保护。它还可以检测到直流,然后防止扬声器音圈被解除。

The CXAR41112 is a stereo, high efficiency, Class-D audio amplifier and is available in TSSOP-28P and QFN4x4- 28B pins packages. The Class-D power amplifier has higher efficiency compared to the traditional Class-AB power amplifier. The filter free Class-D architecture eliminates the external low pass filters. The internal gain setting can minimize the external component counts, and for the flexible application the gain can be set to 4-step 20, 26, 32, 36dB by gain control pins (GAIN0 and GAIN1). The AGC function protects speaker from being out of its power rating but keeps acceptable performance. The integration of Class-D power amplifier is a best solution for high efficiency and low BOM costs. The operating voltage is from 4.5V to 26V. The CXAR41112 power amplifiers are capable of driving 15 W at VDD=16V into 8W speaker, and provides thermal and over-current protections. It also can detect the DC and then prevent the speaker voice coil from being detroyed.
