TLV320AIC3104: Loopback test for SPK & MIC

user6544449

Part Number: TLV320AIC3104

Hello TI team,

How to match the codec SPK output to the input of the MIC at the codec layer, my customer needs to do a loopback test.

Do you have any configuration Profiles and how to do this test？

Thanks !

Hi,

Check 10.4.1.2 in the datasheet to learn how to configure the Line Out/ Mic Bypass path.

Best regards,
Jeff McPherson

Hello ,

I was not find 10.4.1.2 in datasheet, seems we download a different datasheet.

Do you have configuration file?

I don't have a config file at the moment but it's strange that your datasheet doesn't include that section. Does this link take you to the datasheet?: https://www.ti.com/lit/ds/symlink/tlv320aic3104.pdf?ts=1699286465438&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTLV320AIC3104

What is the most recent revision date in the top right of the datasheet?

Thanks,
Jeff McPherson
