Hi Don-san,

We believe that this reason is the combination of the internal digital interpolation filter option and the device variations.
Is our understanding correct?

Hi Don-san,

We doubt that 185mW is typo, this reason is as below.

<Case 1>
DVDD=1.8V
fs=48kHz
Input=Bipolar Zero Data

Prate1=Pmax/Ptyp=185W/48.9W=3.78

<Case 2>
DVDD=1.8V
fs=48kHz
Input=1kHz

Prate2=Pmax/Ptyp=187W/85.2W=2.19

<Case 3>
DVDD=3.3V
fs=48kHz
Input=Bipolar Zero Data

Prate3=Pmax/Ptyp=92.4W/59.4W=1.56

<Case 4>
DVDD=3.3V
fs=48kHz
Input=1kHz

Prate4=Pmax/Ptyp=148.5W/99W=1.50

Could you please advise us about it as soon as possible?

Best Regards,
Kato
