    I'm getting 5v.
    Isn't slew rate the maximum voltage change possible per second(or here us).
    So the maximum change in voltage the sin wave can have is 5v/us.
    if i differentiate the sin wave( A*sin(10^6*t) ):
    I get A*10^6cos(10^6*t)
    The maximum change in voltage is when cos()=1.

    formula is
    SR = 2 * pi * f * Vo
