AD7400 power supply

Hello

Do VDD1 and VDD2  of AD7400 have specification of rising time at power up ?

Our customer's power supply IC to AD7400_VDD output 1.2V~1.6V for a certain period (300us~1ms), and output 5V after that.

Is there any problem with above?

I can not find the specification of rising time at power up in AD7400 datasheet.

If  above  has any conern , please let me know your advice.

Regards,

Terumasa

    Hi Terumasa,

    Ensure that the absolute maximum ratings are not exceeded or violated, then there should be no issue. Additionally, the device should work fine as long as the analog inputs are applied after the supply establishes the 5 V output.
