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.
