    Any signal input with sufficiently fast dV/dT properties could cause a Sallen-Key lowpass #filter to malfunction https://buff.ly/2Y0y69c

    Linear does not mean no distortion

    Distortion: An undesired change in the signal’s waveform after it passes through a device or a system.

    No Distortion
    A system or network (Figure 1) is called distortionless if its output is an exact replica of its input, except for amplitude scaling and time delay

    Linear does not mean no distortion
    From Fig. 2, it seems intuitive that a linear function won’t produce distortion, but a nonlinear function will. It is tempting to conclude that linear circuits are always distortionless systems, but that is not correct. Linear circuits that introduce variation in frequency response (either magnitude or phase) can distort the signal.

    Let’s look at a simple linear circuit, the RC lowpass circuit

    Distortion on purpose
    Distortion is not always a bad thing. There are plenty of applications where distortion is intentionally introduced to accomplish some purpose. A great example of this is the wide range of distortion boxes and other effects used with electric guitars [Ref 3]. Radio frequency design also takes advantage of nonlinear devices to generate harmonics and to mix frequencies together. In high-speed digital links, predistortion is often added to compensate for the characteristics in a transmission line. One person’s distortion is another person’s desired signal.
