ADA4000 comparator

Hi AD,

is the ADA4000-1 can be used as a comparator instead of amplifier and is it a dedicated op-amp to work for this kind of use (e.g comparator)

It seems that ADA4000 is highly sensitive working as a comparator and it doesn't like this non linear mode.

Moreover with a transistor on the output which could create high DV/DT for example.

thanks for your help,

jajajib,

  People use op amps as comparators, but there are several reasons why you don't want to do it.

If you can tell us what supply voltages, signal levels in, logic levels out, response time, etc.

we can suggest a better solution.  Check out the ADCMPnnn parts.
