    Hello Kuwahara-san, 

    Thank you for posting on TI's E2E forum and for your interest in ADS9219!

    There is no specific power up/down sequence to be followed for the ADS9219. 

    Is there a concern for a large discrepancy between power up/down sequence or ramp speeds in a specific system?  Could you please share more on what the expected power up/down rates and order? 

     

    Best regards, 

    Yolanda

    Hello yolanda-san,

    Thank you for your quick answer, understood there is no sequence required.

    The customer just wanted to know if there are any power supply sequence to be followed.
