    Hi Balaji,

    You will need to address the root cause of the issue with your power supply circuit. Adding extra bulk decoupling capacitors on the ADC digital supply can help keep the supply more stable and filter noise. However, if the supply is drooping so low as to register a logic 0 on /RESET, this may not be enough.

    Regards,
