WebbSlew rate (SR) – How fast an op amp can change voltage on its output. An op amp’s output rate of change is limited to the slew rate value. It causes distortion if the signal to be amplified is too fast. Rail-to-rail input – An op amp with a high rail input is able to deal with input signals up to Vcc+ while a low rail input is able to 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.
