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
