LMC ICs sourced from the shop did not work. Carefully read the datasheet and understand its limitations.
However I can answer the main question and give a suggestion for a possible cause of your problem: See the How to Ask page for help clarifying this question. Therefore use the manufacturer’s logo on the top of the LMCN and LMCP Datashest to identify the manufacturer, and then locate the relevant datasheet on their website if you want to find more details.
Is it an analog circuit? I assumed lm741m it’s not possible for 6 chips to be burnt like that Wrong assumption. Yes, post a circuit.

I assumed that it’s not possible for 6 chips to be burnt like that One of my friends had a LMCP IC and I plugged into the same proto board with the same pin configuration and it worked. What is the RS, then?
That fact that one heats up and the other works suggests the pinouts daasheet different. Same input signal as the output. Home Questions Tags Users Unanswered. Addition to that, the IC seems to be heating up a lot. Don’t use it like an op amp.
We can only help when sufficient information is presented; draw a circuit diagram – the small circuit widget in the edit lj741j will open a schematic editor. 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.
Accepted answer provided a better insight! Please clarify your specific problem or add additional details to highlight exactly what you need. However I can answer the main question and give a suggestion for a possible cause of your problem:. Then I tried a non inverting amplifier but that didn’t work too.

Somehow I got the project done perfectly without LMs. If this question can be reworded to fit the rules in the help centerplease edit the question. It dztasheet an audio power amplifier. I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor. But my guess is that they are electrically identical. So the difference could also be described as most?
Can’t figure out what you are talking about. Was just wondering why CN didn’t work when CP did. Should have asked ‘What is the difference between letter N and P at the end of LMC’ instead of giving out details of the project to create a background to the question which made people drove outta their minds: Some other shop sells CP and they work. Shops can get faulty batches dstasheet components, or perhaps counterfeit etc. Olin Lathrop k 30 The LM is not an op amp. Also the is ancient You better use a TL or TL, even those are old but much more suited to many of today’s applications.
Looking carefully at the sequence of events, there seems a possible cause. So I tried creating a basic inverting amplifier using this IC and the oscilloscope showed the same input signal like waveform as the output signal. Unfortunately some parts of your project are unclear. The N and P suffix are packaging; the internal circuit will be equivalent in both parts.
I assumed datashset it’s not possible for 6 chips to be burnt like that.
Just asked this q to get to know what this N and P are! Where do you see the difference now? Do these last letters N and P mean anything like p type or n type? Other packaging type letters are also used, but these can all vary between manufacturers. Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.
No idea what you are doing. When I google, for both ICs, it’s the same datasheet.
