产品简介

CXAR41110是一款立体声、高效率的D级音频放大器，提供TSSOP-28PAndQFN4X4-28针封装。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。filterfree类-D体系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ins（GAIN0和GAIN1）设置为4步20、26、32、36dB。功率限制功能可在输出信号超过扬声器极限额定值时保护扬声器。D类功率放大器的集成是提高功率效率、降低BOM总成本的最佳方案。工作电压8V～26V，CXAR41110功率放大器能在VDD=16V时驱动15W进入8W扬声器，并提供热保护和过流保护，还能检测到防止破坏扬声器音圈的直流电。

The CXAR41110 is a stereo, high efficiency, Class-D audio amplifier available in TSSOP-28Pand QFN4x4-28 pins packages. The Class-D power amplifier has higher efficiency compare to the tradition Class-AB power amplifier. The filterfree Class-D architecture eliminates the external low pass filters. The internal gain setting can minimum the external component counts, and for the flexible application the gain can be set to 4-step 20, 26, 32, 36dB by gain control ins (GAIN0 and GAIN1). The power limit function cans protection the speaker when output signal excess the speaker limit rating. The integration of Class-D power amplifier is a best solution for power efficiency and lower the total BOM costs. The operating voltage is from 8V to 26V. The CXAR41110 power amplifiers are capable of driving 15 W at VDD=16V into 8W speaker, and provides thermal and over-current protections also can detection the DC that prevent to destroy the speaker voice coil.
