ADS131E08S: AVDD power up/down sequence

Part Number: ADS131E08S


Hi,

Let me ask you following questions about AVDD ON/OFF sequence.

Q1) Is it possible to make AVDD and AVDD1(=5V)power ON and OFF while DVDD(=3.3V) is ON?

       If there is something timing condition or sequence to power down, please let me know.

Q2) If the answer of Q1 is yes(=no problem), we have to do the sequence of "11.1 Power-up timing", correct?

       The "reset" is also nessesary to make the device work well?

Q3) TESTP/N pins also connect to AVDD via register.

       I suppose there is also no problem for behabior of the device in this case.

       Is my understanding correct?

Thank you for your support.

Best Regards,

Takumi
