highperformance,dualSinglePoleSingleThrowanalogswitch

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.
