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,

  • Hi,

    I am sorry but I have already mentionned that "I cannot provide with the system circuit" and it is not the purpose of my question. System behaviour of "what I am trying to do" work fine with an other op-amp.

    I try to find the root cause at system level which could lead to op-amp damage but I would like to know more about this op-amp by valuable datas from AD, not general consideration about using op-amp and system analysis.

    So, and maybe you cannot provide with an answer too for other reasons, are there precautions by using this op-amp (not mentionned in datasheet) due to problem on power supply (disymetric, over voltage), ESD, etc ?
