Hi Ido,
Welcome to e2e.
Let me verify if I understand correct your application:
I this correct? This should be possible to do. One thing you should take care of is the DAC output type, if it's class-D you would need an RC low-pass filter between the DAC and the HP amp.
What DAC are you using? We also have some DACs with speaker and HP output drivers like TAS2505 or TLV320DAC3100.

Hi Ivan,

I this correct? This should be possible to do. One thing you should take care of is the DAC output type, if it's class-D you would need an RC low-pass filter between the DAC and the HP amp. OK, I already have filter R=510ohm and cap=2.7nF.
What DAC are you using? WM8524CGEDT,
We also have some DACs with speaker and HP output drivers like TAS2505 or TLV320DAC3100.
I understand but I update an old design
Best regards,
