TIDA-03030: How to drive audio for a USB Typ C Headset

Part Number: TIDA-03030

Hi,

my customer wants to drive a USB Typ C Headset for audio output.

We have looked into TIDA-03030.

The question is what would be the best amplifier in their tool to drive the “3.5mm audio jack” for the TIDA-03030.

The idea is that a tool drives the "3.5mm audio jack" will all be implement in the tool - so not a real connector) and  a headset can be connect to the USB-Typ C connector for audio output.Pls see attached draft.

Ideal would be an audio amplifier with I2C control.

Especially for the pure path devices it isn’t clear how the GND signal is handled (because of move to “mid” potential of the audio signal).

 

Do you have some recommendations on how to drive the audio signal to the TIDA-03030 3.5mm audio jack driving a USB Typ C Headset.
