DESCRIPTION/ORDERING INFORMATION
The TS3A24159 is a dual single-pole double-throw (SPDT) analog switch that is designed to operate from 1.65 V
to 3.6 V. It offers low ON-state resistance and excellent ON-state resistance matching with the
break-before-make feature, to prevent signal distortion during the transferring of a signal from one channel to
another. The device has excellent total harmonic distortion (THD) performance and consumes very low power.
These features make this device suitable for portable audio applications.
