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 make it compliant with the IEC Level 4 ESD standard (IEC 61000-4-2).
