What is clock slew rate?

Slew rate is defined as the maximum rate of change of an op amps output voltage, and is given in units of volts per microsecond.

What is a good slew rate?

Most amplifiers (even the cheap ones) should have a slew rate above 6.3 V/µs. The seemingly high slew rates of most amplifiers are simply good engineering. Having a slew rate that yields a maximum frequency well above the audible range will pretty much eliminate any potential errors and unwanted distortion whatsoever.

What is slew rate formula?

The slew rate formula is (S) = ΔVout/Δt. The slew rate units are V/μs or Volts per second.

What is the purpose of slew rate?

Slew rate helps us identify the maximum input frequency and amplitude applicable to the amplifier such that the output is not significantly distorted. Thus it becomes imperative to check the datasheet for the device's slew rate before using it for high-frequency applications.
