TI TS3A26746E 2x2 Crosspoint Switch for Audio Applications

TI TS3A26746E 2x2 Crosspoint Switch
for Audio Applications

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 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 TI TS3A26746E is ideal for a variety of applications, including cell phones, PDAs, portable instrumentation, digital still cameras, and portable navigation devices.
