ADS131E08S: Power-up sequence and timing

julio campos heado

Part Number: ADS131E08S

Hi,

I am using the ADS131E08SPAGR and our setup has the following power-up sequence (as can be seen in the image): First DVDD powers up to 3.3V then 8ms after AVDD & AVDD1 power up to 2.5V and AVSS & AVSS1 to -2.5V.

I wanted to know if this power-up sequence can have any stability issues or any other issues.

Thank you for your time.

Best regards,

Julio

Hi Julio,

Thank you for your query on the E2E forum. You would have to make sure that the analog input condition is not violated if your analog power supplies are delayed, check the section 7.1 Absolute Maximum Ratings table in the datasheet.

Regards,

Dale
