CXAS4236Q采用Switch Pro技术，是一款双SPTT模拟开关，具有超低失真、高断开隔离度，适用于具有负摆动音频信号容量的特殊立体声音频应用，具有3.3V VCC下0.2Ω（典型）的超低Ron。
CXAS4236Q在3.0V到4.5V的宽范围内操作单个电源，1.8V逻辑与超高PSRR兼容。在每个信号管脚处有一个特殊的点击分路电路，可消除在任何应用条件下（如开关、启用/禁用、断电和通电）的点击和点击。
凭借优越的THD+N性能和其他高性能，CXAS4236Q是高保真系统应用的理想设备。
CXAS4236Q在QFN1826-16L包中提供。所有产品都是无铅和无卤的。

产品概述 返回TOP
With SwitchPro technology, The CXAS4236Q is a Dual SPDT analog switch with ultra-low distortion, high OFF-Isolation for special stereo audio applications with negative swing audio signals capacity that features ultra-low Ron of 0.2Ω (typical) at 3.3V VCC.
The CXAS4236Q operates a single power supply over a wide range from 3.0V to 4.5V and 1.8V logic compatible with ultra high PSRR. With a special pop-click shunt circuitry at each signal pin that eliminates pops and clicks associated at any application conditions likes switched, enable/disable, power-down and power-up.
With superior THD+N performance and other high performance, the CXAS4236Q is an ideal device for Hi-Fi system applications.
The CXAS4236Q is available in QFN1826-16L package. All products is Pb-free and Halogen-free.
