CXAR4176是一款立体声、固定增益、单电源、无盖线路驱动器，有TQFN4x4-20B和TSSOP-16两种产品包。CXAR4176是接地参考输出，无需输出电容器进行直流闭锁。消除输出电容器的优点是节省成本，消除元件高度，提高低频响应。内部固定增益设置（-1.5V/V）可以最大限度地减少外部元件数量，节省PCB空间。高PSRR提高了对噪声和RF整流的抗扰度。CXAR4176的独立关机控制为右通道和左通道。CXAR4176能够将3.3V电压下的2Vrms驱动至600W负载，并提供热保护。

产品概述 返回TOP
The CXAR4176 is a stereo, fixed gain, single supply, and cap-free line driver, which is available in TQFN4x4-20B and TSSOP-16 packages. The CXAR4176 is ground-reference output, and no need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, eliminating component height, and improving the low frequency response. The internal fixed gain setting (-1.5V/V) can minimize the external component counts and save the PCB space. High PSRR provides increased immunity to noise and RF rectification. The independent shutdown control of CXAR4176 is for right channel and left channel. The CXAR4176is capable of driving 2Vrms at 3.3V into 600W load, and provides thermal protection.
