The output voltage of most op amps can swing close to the positive and ...As long as the input voltage V in is lesser than the reference voltage V ref, the output of the op-amp remains positively saturated. When V in goes above the reference voltage, the output of the op-amp switches to its negative saturation level and remains negatively saturated as long as V in is less than V ref. The circuit of a comparator using ...Even for very small differential input, the output of the op-amp will get saturated. Example: if Vd = 1mV and Aol = 10^5, then Vo = 100V. (Theoretically) But the …Op Amp Specifications. Walt Kester, ... James Bryant, in Op Amp Applications Handbook, 2005. Frequency Response—Slew Rate and Full-Power Bandwidth. The slew rate (SR) of an amplifier is the maximum rate of change of voltage at its output. It is expressed in V/S (or, more probably, V/μs). We have mentioned earlier why op amps might have different …

Consider saturation recovery. Typical op amps are not designed to be used as fast comparators, so individual gain stages will go into saturation when the amplifier output is driven to one of its extremes, charging the compensation capacitor and parasitic capacitances. A design difference between amplifiers and comparators is the addition of ...

Now whenever the voltage at the inverting node goes below the voltage -XVsat, then once again the output of the op-amp will become positive saturation voltage because, at that time, the non-inverting node will be slightly less than the inverting node. So, the output will switch from negative saturation voltage to positive saturation voltage.

The amplifier will in this case have no negative feedback and the op amp output will saturate at the negative supply rail. When the input voltage again becomes more positive than the voltage held on the capacitor and the output moves out of saturation the response time of the amplifier will be affected. The circuit may not respond properly to ...
