SCDS186 − FEBRUARY 2005
Description
Features
The TS5A3166 is a single-pole single-throw (SPST)
analog switch that is designed to operate from 1.65 V
to 5.5 V. The device offers a low ON-state resistance.
The device has excellent total harmonic distortion
(THD) performance and consumes very low power.
These features make this device suitable for portable
audio applications.
