3 Description

The TS5A12301E device is a bidirectional, 1-channel,

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 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 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 control input (IN) pin can be

connected to low-voltage GPIOs, allowing it to be

controlled by 1.8-V signals.

The TS5A12301E has ±15-kV air-gap discharge and

±8-kV contact discharge ESD protection for the COM

port to GND, which makes it compliant with the IEC

Level 4 ESD standard (IEC 61000-4-2).
