maximum signal frequency
the maximum frequency at which an op-amp may operate depends on both the bandwidth(BW)and slew rate parameter of the op-amp. for a sinusoidal of general from
the maximum voltage rate of change can be shown to be
signal maximum rate of change =
to prevent distortion at the output, the rate of change must also be less than the slew rate, that is,
so that
additionally, the maximum frequency f in Eq.(10.25)is also limited by the unity-gain bandwidth
example 10.14 for the signal and circuit of fig.10.48, determine the maximum frequency that may be used. op-amp slew rate is SR = 0.5 V/us
