AIC3204 schematic

Hi, Nat,

I already reviewed the schematic and it seems to be correct. I would only suggest to connect the thermal pad to the analog ground plane.

Best regards,

Dear Luis

The following txt is my register setting.

I want to use HP function.

But my HP function does not work.

Could you help me to check? Thanks

Hi, Nat,

I already tested your register configuration on the TLV320AIC3204EVM-K and it works correctly. I obtained the IN1 signal on the HP output.

Could you provide information about the power pins? What voltage values are you using on your circuit?

Best regards,
Luis Fernando Rodríguez S.
