What do you get on the output?Thanks Mr. Ron ! I made the circuit in real life but it didn´t work , any solution ?
the output voltage is 0V , the LM319 doesn´t wanna workWhat do you get on the output?
by " doesn´t work" i mean that the configuration for a comparator do nothing , i don´t if i am clear, sorry for my englishDefine "doesn't work".
I know that working with a pulse width of 1useg is not a good idea working in a breadboard, thats why i used a sinusoidal wave , a triangular wave and a square wave of many frequencies, those signel were compared with a constant voltage value (3.5V) . But i couldn´t get something at the output of the LM319 , just 0V .A 1uS pulse is going to take around 10MHz bandwidth or better to pass. How did you lay out your circuit? If it's on a breadboard with long, loopy interconnecting wires and long leads to your caps, that's where your problem lies.
I dont have it right now, and i´m working in other project, on friday i am going to do that and i´ll post a picture of my breadboard. sorry for the delayDid you try what I suggested in post #9?
Also, post a picture of your breadboard.
i did what you suggest and.... IT FINALLY WORKS.I'll ask for the third time: Did you try what I suggested in post #9?
According to the datasheet, he needs the negative supply if his input swings to ground (see input voltage range spec in datasheet), although, if the other input pin never goes below 3V, it should work OK without the negative supply.If the OP wants a zero to 9 volt peak signal, why is he using a +/- 12V supplies? That would give +/- output.
The OPs hand drawing indicates the input and output signals.
