CXAS4233Q是一款高性能、双单刀单掷（SPST）模拟开关，具有负摆幅音频功能，在3.6V VCC下具有1Ω（典型）的低Ron。
CXAS4233Q在3.3V到4.5V的宽VCC范围内工作，专为高压隔离而设计。EN输入与1.8V逻辑电平兼容。CXAS4233Q还配有智能电路，即使控制电压低于VCC电源电压，也能将VCC泄漏电流降至最低。此功能适合移动手机应用，允许直接与基带处理器通用IO接口，耗电量最小。也就是说，在实际应用中不需要额外的设备来改变控制水平，使之与VCC相同。
由于EN是逻辑高，INx连接到Ox，当模拟信号通过时，非常平坦的Ron从INx连接到Ox使小失真最小化；由于EN是逻辑低，INx断开连接到Ox，Ox承受高达12V的高压，非常有限的耦合返回到INx。
CXAS4233Q有QFN1418-10L包装。标准产品无铅无卤。

产品概述 返回TOP
The CXAS4233Q is a high performance, dual Single Pole Single Throw (SPST) analog switch with negative swing audio capability that features low Ron of 1Ω (typical) at 3.6V VCC.
The CXAS4233Q operates over a wide VCC range of 3.3V to 4.5V and is designed for high voltage isolation. The EN input is 1.8V logic level compatible. CXAS4233Q is also featured with smart circuitry to minimize VCC leakage current even when the control voltage is lower than VCC supply voltage. This feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose IO with minimal battery consumption. In other word, there is no need of additional device to shift control level to be the same as that of VCC in real application.
As EN is logic high, INx connects to Ox, very flatten Ron from INx to Ox minimizes little distortion as analog signals pass through; As EN is logic low, INx disconnects to Ox and Ox is withstanding high voltage up to 12V with very limit couplings back to INx.
The CXAS4233Q is available in QFN1418-10L package. Standard product is Pb-Free and halogen-Free.
