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.
See how the signal is cut. The behaviour of the diode voltage limiter is similar to this circuit:. Sign up using Email and Password. The behaviour of the diode voltage limiter is similar to this circuit: Todor Simeonov 1, 3 Sign up or log in Sign up using Google. Dimitri Petrucci 96 7.

The result will be some kind of oscillator, but it is uncommon. In your second schematic the output of the OpAmp will be like the first waveform, but because of the resitor divider will be scaled satasheet moved up so its minimum is about 0V datazheet its maximum is about 5. Any reason not to use an IC designed to perform as comparator? Update The second schematic is not equal to the first. I updated the post with a modified schematic, that way would be equivalent?

The difference will apper when you close the feedback loop for some exact gain. Home Questions Tags Users Unanswered.

The second schematic is not equal to the first. 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. 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.
But, what if I put a capacitor in the positive feedback? Email Required, but never shown.
