Nov 23, 2, A comparator like mentioned in post 9, or adtasheet you want to use an op amp an LM would do it. Also, I am trying to stay away from IC’s so I can get a better handle on transistor switching first time using them but any ideas with them are welcomed so i know for future use.

Do you already have an account? I couldn’t find a datasheet for LM Why does -9 work? Boy, is that an ugly IC. Could you draw in the resistor values and show how the power is applied?

My questions are essentially: That brings me to a new question, what datasheet specs datasjeet I look for in a comparator? Embedded Systems and Microcontrollers. Why does the op amp output voltage drop so low when the switch is closed and why does it go from on to off and back to on?

Jan 11, 5. Just double checked, it is an LF Jan 11, 7. Jan 11, 26 0. Your name or email address: Posted by dougal in forum: Using a phototransistor as input into comparator Posted by connellyw in forum: Interestingly enough though I had a little time to play around with the circuit and found that if Datsaheet changed R to keep the cap from discharging below.

Any ideas as to why this is, just another issue from the given op amp in use perhaps? No, create an account now. Wayneh, this is the configuration in which it is currently datasueet.

Most of the resistor values are or less, the drain resistor R is 33k, C is uF, op amp output when switch is open is 7. From Lumped Element to Distributed Element Regimes Delving further into the transmission line concept, the boundary between treating the line as a single lumped datasheeet element and using the distributed circuit parameters is investigated with a simple analysis in python.

See common mode range in the data sheet. You May Also Like: You need an IC made to run on a single datasheet.

Do you mean LF? Sep 9, 15, 5, Mar 30, 7, 1, Jan 11, 2.

And everything is great with the split supply, but you get odd behavior when V- is ground? Jan 11, Thanks l3m56 all the replies, I’ll order some proper comparators in the morning. Jan 11, 8. Hey guys, Ive just started to dabble with electronics and thought that this would be a good project to learn about transistors. Yes, my password is: It would work a as a comparator, but it would be a waste.

Jan 11, 9. Jan 13, Op amp as comparator Posted by nickyoko21 in forum: Aug 12, 2, Delay using LM as comparator Reply to Thread. That would destroy the op-amp. Right now I’m just using LEDs to test the circuit and will get adequate components to run the motor, and I removed the resistor from the output to the base.

I assume LM op amp? Jan 11, 4. I think your problem may be that the inputs can only work at 3 volts above the negative supply.

I’m having trouble following.
