Any reason not to use an IC designed to perform as comparator?

Home Questions Tags Users Unanswered. Email Required, but never shown. But, what if I datasheey a capacitor in the positive feedback?
LM comparator and diodes on compensation Ask Question. Similar thing is done on Fig.
The behaviour of the diode voltage limiter is similar to this circuit: Without a datasheet, this is a non-question. The behaviour of the diode voltage limiter is similar to this circuit:. The difference will apper when you close the feedback loop for some exact gain. Open the datasheet from your link lm301a page 16 and look where pin 8 comes from.

The second will work with minimal distortion only with highest impedance inputs – about 1 MegaOhm, while the first can work with kOhm loads without an issue. Would it still work like a comparator? Dimitri Datashewt 96 7. The first makes voltage limiting on the low power circuit of the OpAmp and then the ouput emitter follower as its name says outputs a voltage with similar waveform but with higher load capability.
DimitriPetrucci see the update.
I’m trying to understand what’s the purpose of the two diodes connected to the compensation pin 8and what the output of the comparator is supposed to be. Link to dafasheet datasheet. See how the signal is cut. This will have effect on datashert load you can attach to this circuit.
In your second schematic the output of the OpAmp will be like the first waveform, but because of the resitor divider will be scaled and moved up so its minimum is about 0V and its maximum is about 5.
