CXAR41192是一个2Vrms到3Vrms的无需点击/弹出立体声线路驱动程序，设计用于移除输出直流阻塞电容，以减少组件数量和成本。该器件是单电源电子器件的理想选择，其中尺寸和成本是关键的设计参数。
CXAR41192能够在3.3V电源电压下将2Vrms驱动至2.5kΩ负载。该器件具有差分输入，并使用支持±1V/V至±10V/V增益范围的外部增益设置电阻器。使用外部增益电阻器还允许实现二阶低通滤波器，以补充DAC和SOC转换器。CXAR41192具有内置的关闭控制，用于弹出/单击自由打开/关闭控制。
与生成2Vrms输出的传统方法相比，在音频产品中使用CXAR41192可以减少组件计数。CXAR41192不需要大于3.3V的电源来产生5.6VPP输出，也不需要分轨电源。CXAR41192集成了一个电荷泵，以产生一个负电源轨，提供一个干净的，点击/自由地面偏置2Vrms输出。

产品概述 返回TOP
The CXAR41192 is a 2Vrms to 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters.
The CXAR41192 is capable of driving 2Vrms into a 2.5kΩ load with 3.3V supply voltage. The device has differential inputs and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd-order low pass filter to compliment DAC's and SOC converters. The CXAR41192 has build-in shutdown control for pop/click-free on/off control.
Using the CXAR41192 in audio products can reduce component count compared to traditional methods of generating a 2Vrms output. The CXAR41192 doesn't require a power supply greater than 3.3V to generate a 5.6VPP output, nor does the device require a split rail power supply. The CXAR41192 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 2Vrms output.
The CXAR41192 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -40℃ to +85℃.
