AD8604

Hello everyone,

can I use the AD8604 in an environment with two power supplies? E.g. -3V3 and +3V3?

Thanks in advance
Andreas

    Hi Andreas,

    AD8604 can work with dual supply provided that it’s total supply span/range is less than its absolute maximum rating of 6V, to ensure proper functionality and device reliability. In your case, if you will use -3.3V/+3.3V, that is equivalent to a  6.6V supply range and you will violate the Abs Max Rating and would not guarantee the product’s performance, functionality and reliability. For optimum device performance, it is recommended to use 2.7V to 5V single supply or equivalent of +/-1.35V to +/-2.5V in dual supply. Hope this helps.
