产品概述 返回TOP
The CXAS42247 CXAS42248 is a low on-resistance, SPDT (Single-Pole/Double-Throw) analog switch that operates from a 2.25V 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 CXAS42247 CXAS42248 has a separate logic supply pin (VIO) that is characterized to operate from 1.65V to 1.95V. VIO powers the control circuitry, which allows the CXAS42247 CXAS42248 to be controlled by 1.8V signals.The CXAS42247 CXAS42248 is available in the WLCSP2X4-8 package.
