Homework Help: Need help with a circuit with Op-amp and Diodes

  1. Jul 27, 2010 #1
    1. The problem statement, all variables and given/known data

    Hello,

    It would be very appreciated if someone could give me any orientation in this problem:

    3. The attempt at a solution

    (1) I do not understand very well how Vout is changed from -VDD to VDD, however, I wonder if the following would be ok...

    When Vout = -VDD, DA is ON, DB is OFF
    When Vout = VDD, DB is ON, DA is OFF

    Could someone please orientate me with this problem ? I have only dealt with very basic op-amp circuits....

    Thanks in advance...
