Hi,


To follow power sequence as per power supply recommendations suggested in data sheet, please suggest the IC to incorporate in our design.

please confirm whether power sequence is to be followed strictly or we can bypass it.

    Hi, Satya,

    The audio codecs are not sensitive to power supply sequences. Specially, the power supplies sequences are not required if the hardware configuration is correct. So, I recommend to follow the datasheet layout indications in order to avoid rare conditions that will require power sequences. Basically, we recommend to separate the digital activity from the analog activity. The analog portion of the audio codec is sensitive to the digital activity. So, please separate the analog lines from digital lines in the hardware design. For additional tips, please take a look at the wiki article below:
