Texas Instruments TS3A26746E 2x2 Crosspoint Switch
Texas Instruments TS3A26746E 2x2 Crosspoint Switch for Audio Applications is used to interchange the Ground and MIC connections on a headphone connector. The TI TS3A26746E Crosspoint Switch features a Ground switch with an ultra-low RON of <0.1Ω to minimize the voltage drop across it, preventing undesired increases in headphone ground reference voltage. The switch state is controlled via the SEL input. When SEL=High, GND is connected to RING2, and MIC is connected to SLEEVE. When SEL=Low, GND is connected to SLEEVE, and MIC is connected to RING2. An internal 100k pull-up resistor on the SEL input sets the default state of the switch. The Texas Instruments TS3A26746E is ideal for a variety of applications, including cell phones, PDAs, portable instrumentation, digital still cameras, and portable navigation devices.Features
