This will have effect on the load you can attach to this circuit. Would it still work like a comparator? As long as the OpAmp works in a open feedback loop as a dstasheet no feedback connection, maximum gain both will output similar waveforms.

Dimitri Petrucci 96 7. Email Required, but never shown. But, what if I put a capacitor in the positive feedback?
Similar thing is done on Fig. 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.
Update 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. The behaviour of the diode voltage limiter is similar to this circuit: Sign up or log in Sign up using Google.
The datasheeh will be some kind of oscillator, but it is uncommon.
Any reason not to use an IC designed to perform as comparator? Post as a guest Name. Open the datasheet from your link on page 16 and look where pin 8 comes from.

The behaviour of the diode voltage limiter is similar to this circuit:. The second schematic is not equal to the first.
DimitriPetrucci see the update. Link to the datasheet. Todor Simeonov 1, 3 Without a datasheet, this is a non-question.
