Other Parts Discussed in Thread: PCM1795, PCM1792

Hi all

Could you let me know whether PCM1795 can be used instead of PCM1704U ? in an old design so no possibility to reinvent !

Thanks

If not, what would you advise ?

    Bill,

    What are your system requirements?  Are you looking for a  pin-to-pin compatible option, or are you able to have some flexibility?  I don't believe we have any pin-to-pin compatible alternatives.  The PCM179x is a good start for >120dB DNR performance, though the 1795 is 32 bits and other devices such as the PCM1792 are 24 bits (and lower noise floor).  If a DNR spec is more 111dB range (like the PCM1704) then the 20-pin H/W programmable PCM510x family may be good as well.
