ADS1299: Regarding the power-on timing of the ADS1299

kenichi takahashi

Part Number: ADS1299

Tool/software:

I plan to use it with AVDD: +2.5V, ADSS: -2.5V, and DVDD: +3.3V.

Will it be damaged if ADSS is applied later than AVDD?

    Hello Takahashi-san,

    The device should behave normally as long as the Absolute Maximum Ratings are not violated. If AVDD ramps first before AVSS, what is the expected voltage on AVSS? Will it be held near ground until -2.5V has ramped?

    Regards,

    Ryan
