1、? ? ? ? ? SCDS174A AUGUST 2004 REVISED SEPTEMBER 2004 Description The TS5A3159 is a single-pole double throw (SPDT) analog switch that is designed to operate from 1.65-V to 5.5-V. The device offers a low ON-state resistance and an excellent ON-resistance, matching with the break-before-make feature
2、to prevent signal distortion during the transferring of a signal from one channel to another. The device has an excellent total harmonic distortion (THD) performance and consumes very low power. These features make this device suitable for portable audio applications. Applications ?Cell Phones ?PDAs
