Dale Link to the datasheet. Open the datasheet from your link on 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. Similar thing is done on Fig. LM comparator and diodes on compensation Ask Question.

Doutaxe Post as a guest Name. The second schematic is not equal to the first. But, what if I put a capacitor in the positive feedback? The difference will apper when you close the feedback loop for some exact gain.
The result will be some kind of oscillator, datasneet it is uncommon. Sign up or log in Sign up using Google. 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. The behaviour of the diode voltage limiter is similar to this circuit:.
Dimitri Petrucci 96 7. LM comparator and diodes on compensation Ask Question. The first makes voltage limiting on the low power circuit of the Daatsheet and then the ouput emitter follower as its name says outputs a voltage with similar waveform but with higher load capability.

The behaviour of the diode voltage limiter is similar to this circuit: See how the signal is cut. Would it still work like a comparator? Todor Simeonov 1, 3 Update The second schematic dahasheet not equal to the first. As long as the OpAmp works in a open feedback loop as a comparator no feedback connection, maximum gain both will output similar waveforms. DimitriPetrucci see the update.
