Open the datasheet from your link on page 16 and look where pin 8 comes from.

Without a datasheet, this is a non-question. 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. Post as a guest Name. LM comparator and diodes on compensation Ask Question.
The behaviour of the diode voltage limiter is similar to this circuit:. I updated the post with a modified schematic, that way would be equivalent?
Any reason not to use an IC designed to perform as comparator? Sign up using Email and Password. The second schematic is not equal to the first.

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. Link to the datasheet. The dxtasheet will apper when you close the feedback loop for some exact gain. Sign up using Facebook. See how the signal is cut.
In your second schematic the output of the OpAmp will be like the first waveform, but because of datassheet resitor divider will be scaled and moved up so its minimum is about 0V and its maximum is about 5. The result will be some kind of oscillator, but it is uncommon.
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 behaviour of the diode voltage limiter is similar to this circuit: Home Questions Tags Users Unanswered. Email Required, but never shown. Update The second schematic is not equal to the first.
