    Hi,

    I am trying to understand the working of single ended to differential converter circuits using op amps. I am a bit familiar with op amp having one output but in this case, an op amp with two outputs has been used which is creating difficulty in comprehending its working. Any help regarding the circuit working/interpretation will be appreciated. Please find the attached circuit image as well.

    hi Q,
    In order to understand your problem, could you give an example of a feature you do not understand, perhaps it will help us in answering your query.

    Actually i am unable to understand how the input has been divided b/w 2 outputs. I can understand op amp circuits with a single output but how is the second output being produced by this circuit?

    hi.
    Its basically two OPA's configured as shown in this clip, from a d/s.
