Home Questions Tags Users Unanswered. Any reason not to use an IC designed to perform as comparator? I updated the post with pm301an modified schematic, that way would be equivalent? Update The second schematic is not equal to the first. The difference will apper when you close the feedback loop for some exact gain.

The second schematic is not equal to the first. The behaviour of the diode voltage limiter is similar to this circuit: Sign up using Email and Password.

LM comparator and diodes on compensation Ask Question. Open the datasheet from your link dstasheet page 16 and look where pin 8 comes from.

See how the signal is cut. But, what if I put a capacitor in the positive feedback?

Without a datasheet, this is a non-question. As long as the OpAmp works in a open feedback loop as a comparator no feedback connection, maximum gain both will output similar waveforms. The first makes voltage limiting on the low power lm30an 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’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 result will be some kind of oscillator, but it is uncommon. This will have effect on the load you can attach to this circuit.

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.

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.

Would it still work like a comparator?
