PCM1681: Is there any spec difference between narrow mode and wide mode?

Hello team,

PCM1681 have 2 modes, narrow and wide.

All of electrical characteristics are specified with narrow mode.
Is there any spec difference between narrow mode and wide mode?

I care about difference about audio quality and current consumption.

Best regards,
Koyo

    Hi Koyo-san,

    The narrow filter mode is the same as the "sharp roll-off" filter.  The wide filter mode is the same as the "slow roll-off".

    There should not be any difference in current consumption or audio quality (except subjectively).

    Thanks,

    Paul
