Hi everyone, I wonder if you could educate me a bit, I am trying to understand what the purpose of a differential output op-amp would be. Can anyone help me here, can I leave the inverted-output floating and only use the non-inverted output ? thanks in advance Steve -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
