    hi everyone
    i want to know how to read these specifiaction from op-amp OPA548 datasheet:
    minimum gain
    power bandwidth
    small signal bandwidth
    for power bandwidth i found this equation:
    fpw=SR/(2*pi*Vmax)

    Minimum gain = 90dB

    Power bandwidth is from either the Maximum Output Swing graph on page 6 or calculated from the last equation in your post.

    Small signal bandwidth is the 1MHz GBWP divided by the closed-loop gain of the circuit.
