WAS4732D Datasheet (WillSEMI) - MIC/GND Cross-point Switch

WAS4732D, MIC/GND Cross-point Switch

The WAS4732D is a 2x2 cross-point switch that is used to interchange the Ground and MIC connections on a headphone connector.

The Ground switch has an ultra-low Ron of 0.1 Ω (typical) to minimize voltage drop across it, preventing undesired increase in headphone ground reference voltage.
