Webb20 nov. 2016 · The op-amp (used as a comparator with hysteresis proportional to the supply voltage as determined by the R1/R2 ratio) has a finite slew rate and thus the edges of the square wave are really ramps. Thus the square wave spends less time at the limits. The most important reason as to why op-amps are slew-rate limited is stability. Amplifiers with a high enough gain at a frequency when the output phase shift is above 180 degrees can oscillate. A high slew rate means that the signal contains high-frequency components, which can lead to problems. A … Visa mer The meaning of Slew ratebasically refers to how fast the op-amp is capable of changing its output voltage in response to a change in input. Slew … Visa mer The output swing is deliberately limited in op-amps to ensure stability through the use of a compensation capacitor, which limits the output slew … Visa mer The LM741 is a classic op-amp that has been around for a very long time and is the perfect specimen for this example.
