Dear support team,
My customer wants to know internal over sampling rate of sigma delta DAC in ADAU1401A.
Could you tell me about it,please?

Hi Yabune-san,
At 44.1 kHz and 48 kHz rates, the filters are 128x oversampling.
At 88.2 kHz and 96 kHz rates, the filters are 64x oversampling.
Dear Brett-san,
Thank you very much!!
Best regards,
Takehiro Yabune
