Open the datasheet from your link on page 16 and look where pin 8 comes from. Update The second schematic is not equal to the first. Any reason not to use datashewt IC designed to perform as comparator? Without a datasheet, this is a non-question.
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. Dimitri Petrucci 96 7.
As long as the OpAmp works in a open feedback loop as a comparator no feedback connection, maximum gain both will output similar waveforms. See how the signal is cut. Home Questions Tags Users Unanswered.
Sign up using Facebook. The second will work with minimal lm301qn only with highest impedance inputs – about 1 MegaOhm, while the first can work with kOhm loads without an issue. Sign up using Email and Password. The result will be some kind of oscillator, but it is uncommon.
Link to the datasheet. Email Required, but never shown. DimitriPetrucci see the update.
Post as a guest Name. 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.

I updated the post with a modified schematic, that way would be equivalent? But, what if I put a capacitor in the positive feedback? The behaviour of the diode voltage limiter is similar to this circuit:. Sign up or log in Sign up using Google.
This will have effect on the load you can attach to this circuit. In your second schematic the output of the OpAmp will be dataxheet the first waveform, but because of the resitor divider will be scaled and moved up so its minimum is about 0V and lm301ann maximum is about 5.
LM comparator and diodes on compensation Ask Question. The behaviour of the diode voltage limiter is similar to this circuit: Similar thing is done on Fig.
