Part Number: PCM1793

Hi team,

The PCM1793 datasheet shows load impedance and it's defined as dc load.

Is there load impedance defined as ac coupled?

Hi Hayashi-san,

Footnote (2) defines this load as a DC-coupled load.

Thanks,
Paul

Hi Paul,

Yes, I know 1.7kohm is defined as DC-coupled load.

I'd like to know how much is the load impedance as AC-coupled load.

Regards,

Hideki

Hi Hideki,

Sorry for the misunderstanding. I would expect the AC coupled load could be 50% of the DC load minimum so that the peak current is still the same limit.

Thanks,

Paul
