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? …

Ranita,
Yes, you may use a GPIO pull down the DET_TRIGGER pin to ground creating a high to low signal that will initiate the TS3A227E detection sequence.
For USB Type C audio applications I would also take a look at this blog and reference design…
Hi Mike,
You cannot route Type-C analog audio through the TPS65982 mux due to the voltage swing. The image below shows the pin mapping for the Type-C connector as an audio accessory output.
The TPS65982 will hi-Z its outputs to allow for an external…

Micheal,
If you are looking to place bipolar audio signals on the USB Type C connector take a look the TIDA00565 reference design.
Are you referencing the spec below stating the current limit through the shunt resistor is 10mA? The 10mA spec…
Alex,
We have a couple of choices like the TS5USBA224 device that can eliminate the undesirable audible click and pop when switching in an audio path. Other devices with this feature include the TS3USBA25 and TS5A22364.
1. Are there any reference…
