Hi TI expert.

Could you review schematic for PCM1861 & PCM1754?

PCM1861 will be using slave mode.

Thanks

    Hi Downey,

    The schematic looks good, just a couple things to mention for PCM1861:

    1) Are you supplying 1.8V to the LDO to bypass it or is this the LDO output? If you are going to input 1.8V to bypass the internal LDO then IOVDD must also be 1.8V

    2) I would make sure your anti-aliasing capacitors are C0G/NP0 so that they don't introduce distortion at higher signal levels.

    You may want to post another thread with PCM1754 part number as this product is supported by a different group and they won't see this thread unless it is associated with that part number!

    Best,

    Zak
