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 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.
