Operational Amplifiers - Saturation

  1. Mar 15, 2014 #1
    I am an A level physics student. I have a doubt regarding the saturation of op-amps. For a circuit with a dual power supply, each supply has an emf VS. My doubt is, why is the MAXIMUM magnitude of the output voltage VS? Shouldn't it be VS - (- VS) = 2VS? (Since the potential difference is the difference in potential between the two terminals).

    Please post a link to the datasheet and give us a pointer to the specification that you have the doubt about. That is the most efficient way to get your question answered. :smile:

    As Berkeman suggests, it entirely depends on how the output voltage is defined for that specific op amp.
