Op-Amp Slew Rate/Gain-Bandwidth Product

  1. May 28, 2012 #1
    Question
    The op-amp selected for the unity gain inverter, has a gain-bandwidth product, and maximum slew rate at its output of 1V/μs[/b]
    (i) Justify the statement that a high gain-bandwidth product necessarily leads to a high slew rate
    (ii) The phase sensitive detector is expected to operate with a reference frequency set at 100kHz. Based on the slew rate given, determine a maximum rms voltage for input signals and explain your reasoning
    My problem
    Don't really know where can I get the gain-bandwidth product. I feel there's no need to present my attempt at a solution, because it's not the type of question that will require derivation or anything.
    Thanks for your help (in advance)

    An op amp outputs a voltage V0sin(ωt). What's the maximum slew rate?

    (I hate to muddy the water, but actually the statement is not necessarily correct. Hint: it depends on the max output voltage required).

    Sorry, stupid question. Just needed to differentiation once.
