WAS4732D WAS4732D MIC/GND Cross-point Switch for EU/US Headphone Compatible Application http://www.sh-willsemi.com Descriptions 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. the switch state is controlled via the SEL input. When SEL=High, GND is connected to COM2 and MIC is connected to COM1; When SEL=Low, GND is connected to COM1 and MIC is connected to COM2. An internal pull-down 2MΩ resistor on SEL input sets the default state of the switch. The WAS4732D is available in DFN2x2-6L package. Standard product is Pb-Free and halogen-Free. Features  Supply voltage : 2.3 ~ 5.0V  ultra-low Ron for GND Switch : 100mΩ  low Ron for MIC Switch : 4.5 Ω  Break-Before-Make Switching  Low quiescent current over an Expanded Co...
