The CXAS4231D 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 CXAS4231D is available in DFN2x2-6L package. Standard product is Pb-Free and halogen-Free.
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 Control Input Range
ESD Rating (HBM JEDEC: JESD22-A114)
IO to GND : ± 8KV
Power to GND : ± 5KV
