same circuit, then that strongly suggests that the LMCN ICs were faulty. I tried 4 other CN ICs I bought from the shop the same day and all not working. CN. LMCN/NOPB. ACTIVE. PDIP. P. 8.

Just asked this q to get to know what this N and P are!

CN Datasheet(PDF) – Fairchild Semiconductor

You need to buy this as suitable for your motor and battery – it’s NOT something you’re going to be able to build yourself!. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Started by Silverboy Today at 7: So, I would suggest you start searching and reading!

We can only help when sufficient information is presented; draw a circuit diagram – the small circuit widget in the edit controls will open a schematic editor.

Can’t figure out what you are talking about. I wish I could think of a good analogy to make it easier to understand, but nothing good comes to mind, maybe someone else can think of something.

Forums New posts Search forums. Carefully read the datasheet and understand its limitations. So the difference could also be described as most? Some other shop sells CP and they work. I don’t plan on doing your work for you but I don’t mind helping you. Don’t use it like an op amp. Wow, good thing I asked for details! The project description was to create a background.

LM 741CN Amplifier

They sell only CNs. So basically an amplifier with a gain of Mosfet drain current spike and input current spike in full bridge inverter. By continuing to use this site, you are consenting to our use of cookies.

No idea what you are doing. LMC ICs sourced from the shop did not work. Accepted answer 741xn a better insight! However I can answer the main question and give a suggestion for a possible cause of your problem: Why can’t they just answer the question asked in the heading?

I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor. Therefore it seems possible that some or all of your problems could be explained by a faulty or counterfeit batch of LMCN ICs, since at least 4 of them from your story came from the same source. The N and P suffix are packaging; the internal circuit will be equivalent in both parts. Hang on just a second, we shouldn’t presume someone’s first language is English 741cnn because they live in an English speaking area, perhapps we should have a separate box for first language.

When I google, for both ICs, it’s the same datasheet. 741xn circuit for temp sensing using diodes Started by Elerion Today at 1: Started by chemelec Today at 4: Home Questions Tags Users Unanswered.

Hero Banned May 25, Shops can get faulty batches of components, or perhaps counterfeit etc. Blogger 1 The output can’t “add” to the 7411cn voltage in the way you are thinking, because that would imply that the ground reference 471cn the output was the input voltage, which it’s not.

With most ESC’s, you plug in a main large battery to the ESC, the ESC has a wire which supplies power to your receiver which no longer requires its own batteryand has another wire that plugs into the receiver in place of the throttle servo that would have been in your gas model, and then of course the motor is connected to the ESC. However I can answer the main question and give a suggestion for a possible cause of your problem:. The LM is not an op amp.


Hi, Im working on a project of mine and i have a small prob wich I hope you guys can help me with. Since you are planning to use batteries a floating power source it might be possible to come up with some circuit 471cn would do this kind of “addition” to the original input 741cj that you seem to want, however I think it would be a pretty poor design with different grounds, and probably not a good idea for a beginner to tinker with, because it would almost certainly be more complex to build and debug than the incredibly simple non-inverting amplifier configuration.

CN (Fairchild) – Single Operational Amplifier

In this context, no. Welcome to our site! Then I tried a non inverting amplifier but that didn’t work too.

Here I’ve added the circuit diagram I used to create the inverting amplifier. Hero Banned May 27, What is the RS, then? Thread starter atntias Start date May 25, The receiver on the car should output a servo pulse? How to create dashed plot in Octave? Perhaps if you explained some more details of what you’re trying to accomplish then we could provide some more insight. I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption. A quick Google for op-amp inverting amplifier has revealed some helpful hints.
