The second schematic is not equal to the first. I updated the post with a datashheet schematic, that way would be equivalent? Sign up using Facebook. Sign up using Email and Password.

DimitriPetrucci see the update. The difference will apper when you close the feedback loop for some exact gain.
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.

See how the signal is cut. The behaviour of the diode voltage limiter is similar to this circuit:. This will have effect on the load you can attach to this circuit. Would it still work like a comparator?

As long as the OpAmp works in a open feedback loop as a comparator no feedback connection, maximum gain both will output similar waveforms. 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.

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. Todor Simeonov 1, 3 Without a datasheet, this is a non-question.
Dimitri Petrucci 96 7. LM comparator and diodes on compensation Ask Question. Open the datasheet from your link on page 16 and look where pin 8 comes from. 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.
