CXAR4175是一款立体声、单电源、无盖线路驱动器，有TQFN4x4-20B、TSSOP-16和SOP-14三种型号。CXAR4175是一个接地参考输出，不需要输出电容器进行直流阻塞。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。建议使用-1V/V至-10V/V的外部增益设置。高PSRR提高了对噪声和射频整流的免疫力。CXAR4175的独立关机控制用于右通道和左通道。CXAR4175能够在3.3V电压下将2Vrms驱动至600W负载，并提供热保护

产品概述 返回TOP
The CXAR4175 is a stereo, single supply and cap-free line driver, which is available in TQFN4x4-20B, TSSOP-16, and SOP-14 packages. The CXAR4175 is a ground-reference output and doesn’t 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 external gain setting is recommended using from -1V/V to -10V/V. High PSRR provides increased immunity to noise and RF rectification. The independent shutdown control of CXAR4175 is for right channel and left channel. The CXAR4175 is capable of driving 2Vrms at 3.3V into 600W load, and provides thermal protection
