AD8465 Power Sequence

Category: Hardware
Product Number: AD8465
Software Version: -

I am using the AD8465 part in a front-end electronics design, the first two amplification stages are powered by a different supply than the AD8465.  Is there any issue with the AD8465 receiving an input signal while it is not powered?

    Hello  ,

    There is a possibility that the absolute maximum ratings will be reached if the AD8465 is not yet powered on. It is advisable to power on the comparator first before inputting signals.
