Other Parts Discussed in Thread: TS3A26746E, TS3A227E

Hi Expert,

I found the TI design for Type C audio solution, that used the TS3A227E swithc for microphone and GND. But some data used TS3A26746E. I have some question.

1. Which one is better?

2. Does TS3A226A also support it?

3. Does any risk for auto detect Mic or GND for Type C application? (TS3A226A or TS3A227E)

Thanks!
