The second schematic is not equal to the first. But, what if I put a capacitor in the positive feedback?

Update The second schematic is not equal to the first. See how the signal is cut. Open the datasheet from your link on page 16 and look where pin 8 comes from. 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.

The behaviour of the diode voltage limiter is similar to this circuit:. Without a datasheet, this is a non-question.

The behaviour of the diode voltage limiter is similar to this circuit: Sign up or log in Sign up using Google. Todor Simeonov 1, 3 As long as the OpAmp works in a open feedback loop as a comparator no feedback connection, maximum gain both will output similar waveforms.

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?

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. Sign up using Facebook.

The result will be some kind of oscillator, but it is uncommon. Sign up using Email and Password. Email Required, but never shown. 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’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. Any reason not to use an IC designed to perform as comparator?
