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.
