The TS5A21366 is a bidirectional, 2-channel, single-pole single-throw (SPST) analog switch that is designed to operate from 1.65-V to 5.5-V supply voltages. The device offers a low ON-state resistance and an excellent channel-to-channel ON-state resistance matching. The device has excellent total harmonic distortion (THD+N) performance and consumes very low power.

The control pin can be connected to a low voltage GPIO allowing it to be controlled by 1.8-V signals.

These features make this device ideal for portable audio applications.

The TS5A21366 is available in a small, space-saving 8-pin DCU or RSE package, and is characterized for operation over the free-air temperature range of –40°C to 85°C.
