Audio Switch

GT4798

The GT4798 is an audio headset analog switch that is used to detect 3.5mm accessories and switch SLEEVE and RING2 by external controller. The ground signal is routed through a pair of low-impedance ground FETs (70mΩ TYP), resulting minimal impact on audio crosstalk performance. The ground FETs of the device are designed to allow FM signal pass-through, making it possible to use the ground line of the headset as an FM antenna in mobile audio application.

The GT4798 operates over an ambient temperature range of -40°C to +85°C.
