Other Parts Discussed in Thread: ADS8568

Hello, to whom it may concern,

Please tell me about power sequence of ADS8568.

Our customer is considering like a following power sequence.

Is there no problem?

 => ±12V（HVDD、HVSS） →5V（AVDD) → Wait until the stability → 3.3V（DVDD）

If it has any problem between AVDD and DVDD,could you please tell me any advice and solution?

Best regards,

Manabu Ito

    Hi Manabu

    Generally, there are no specific requirements with regard to the power sequencing of the device. However, when HVDD is supplied before AVDD, the internal electrostatic discharge (ESD) structure conducts, increasing the IHVDD beyond the specified value until AVDD is applied.

    Please let me know if you need more information.

    Can you please let me know about End application

    Thanks & Regards
