Link to the datasheet. Home Questions Tags Users Unanswered. The second will work with daatsheet distortion only with highest impedance inputs – about 1 MegaOhm, while the first can work with kOhm loads without an issue.

But, what if I put a capacitor in the positive feedback? Sign up using Facebook. Without a datasheet, this is a non-question.
Any reason not to use an IC lm301qn to perform as comparator? This will have effect on the load you can attach to this circuit. The second schematic is not equal to the first.
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 lm3301an. I updated the post with a modified schematic, that way would be equivalent? The behaviour of the diode voltage limiter is similar to this circuit:.
As long as datasheeh 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.
Dimitri Petrucci 96 7. The difference will apper when you close the feedback loop for some exact gain.
Todor Simeonov 1, 3 Would it still work like a comparator? LM comparator and diodes on compensation Ask Question.

The behaviour of the diode voltage limiter is similar to this circuit: See how the signal is cut. Sign up or log in Sign up using Google. Open the datasheet from your link on page 16 and look where pin 8 comes from. 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.
