CXAR4182是一种立体声、差分输入、单电源和无盖线路驱动器，可在MSOP-10P包中提供。CXAR4182是接地参考输出，不需要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。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校正的免疫力。CXAR4182具有Depop解决方案的关机和欠压检测功能。CXAR4182能够在3.3V电压下将2.1Vrms驱动至2.5kW负载，并提供短路和热保护。

产品概述 返回TOP
The CXAR4182 is a stereo, differential input, single supply, and cap-free line driver, which is available in MSOP-10P package. The CXAR4182 is 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. CXAR4182 has shutdown and under-voltage detector function for Depop solution. The CXAR4182 is capable of driving 2.1Vrms at 3.3V into 2.5kW load, and provides short-circuit and thermal protection.
