Hi Team,

Could you please advise if we have any device similar to the AK4127? 

Thanks!

    Hi Roy,

    Thanks for attaching the DS for the AK4127. Reviewing the same, this is stereo SRC w. DR of -140dB in addition to being a HW controlled device. I am not sure what specs we are trying to hit at a system level, but if we need to meet DR value, I would recommend SRC4192...if we can live with -125dB, you can target SRC4190 as well.

    Below table is a brief comparison for all 3 devices.

    NOTE that the TI devices support WIDE Input to Output sampling rate compared to the AK part. Finally, I did review the group delay #s and we should be comparable in that area as well, but it would be good to know the actual spec from customer to see what the design requires.

    Hope this helps.

    Best regards,
    Ravi
