    Summary

    Description
    English: Slew limiting may distort large or fast signals. A 250 kHz input sine (magenta) is buffered by an opamp with a 720 mV/μs slew limit. With a small input sine, the output (yellow) has almost no distortion. But as the input's amplitude increases, the output can't transition fast enough to reproduce the larger sine's steeper slope and looks more like a triangle wave.

    Note: I generated this using a MCP6004 opamp and a Hantek 6254BD oscilloscope.

    An opamp's slew limit may distort its output. A 250 kHz sine input (magenta) is fed into an opamp voltage buffer with a ~720 mV per microsecond slew limit. With input's starting amplitude of 400 mV the output has almost no distortion.
