DESCRIPTION

The TS5A26542 is a dual single-pole double-throw (SPDT) analog switch that is designed to operate from 2.25 V

to 5.5 V. The device offers a low ON-state resistance with an excellent channel-to-channel ON-state resistance

matching, and the break-before-make feature to prevent signal distortion during the transferring of a signal from

one path to the 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.

The TS5A26542 has a separate logic supply pin (VIO) that operates from 1.65 V to 1.95 V. VIO powers the control

circuitry, which allows the TS5A26542 to be controlled by 1.8-V signals.
