Other Parts Discussed in Thread: TLV320AIC3104
Hi Steve,
I checked on E2E, and find below link with similar topic and question that I would like to get help with.
So here writing to you to check for help.
To use HPLOUT and HPROUT as single end output, as you suggested in below link register 58/ 72 for HPL/ROUT need to be power-down.
Could you help suggest what’s the reasons ?
My customer would like to use TLV320AIC3104-Q1 for one Headphone output application, and DAC path is only used.
See as attachment schematic design and register dump, and below initialization registers configuration.
Now we have met issue that we could not get output at HPL/ROUT, and check the register dump that there is short fault reported at register 95.
Could you help check if it’s really similar issue as below ? (I would ask customer to help try change and test tomorrow.)
And do you see any other issues for customer sch. design that need to be improved ?
Also, for the TLV320AIC3104 initialization, is there any specific sequence required ? I check it in spec, and seems the sequence now we use is matched.
Thanks a lot for your help in advance.
