产品概述 返回TOP
The CXAS42249 CXAS42249A CXAS42249B CXAS42250 is a low on-resistance, SPDT (Single-Pole/Double-Throw) analog switch that operates from a 1.65V to 5.5V supply. The device offers an excellent ON-resistance matching, and low total harmonic distortion (THD) performance. The device is designed for fast switching speeds with the breakbefore-make feature to prevent signal distortion during the transferring of signal from one channel to another. These features make this device suitable for portable audio applications. The CXAS42249/A/B CXAS42250 is available in the SC-70-6 (SOT-363) and WLCSP2X3-6 package.
