What is the RS, then? Some other shop sells CP and they work. 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. So the difference could also be described as most? 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.

Blogger 1 Can’t figure out what you are talking about. I assumed that it’s not possible for 6 chips to be burnt like that. Unfortunately some parts of your project are unclear.

Please clarify your specific problem or add additional details to highlight exactly what datasheet need. Just to ,m741j you know, this description of your project doesn’t datasjeet sense e.

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. The LM is not an pm741j amp. Shops can get faulty batches of components, or perhaps counterfeit etc.


Is it an analog circuit? It is an audio power amplifier. That fact that one heats up and the other works suggests the pinouts are different. Just asked this q to get to know what this N and P are! Depending where your shop sourced the components, then these are some of the possibilities you should consider.

Yes, post a circuit. Other packaging type letters lm7441j also used, but these can all vary between manufacturers. Addition to that, the IC seems to be heating up a lot. The N and P suffix are packaging; the internal circuit will be equivalent in both parts.

Was datasheer wondering why CN didn’t work when CP did. Why can’t they just answer the question asked in the heading? Accepted answer provided a better insight! In this context, no. See the How to Ask page for help clarifying this question. Carefully read the datasheet and understand its limitations.

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: If this question can be reworded to fit the rules in the help centerplease edit datashewt question.

I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption. They sell only CNs. LMC ICs sourced from the shop did not work. Datashedt use it like an op amp. When I google, for both ICs, it’s the same datasheet. The project description was to create a background.

Somehow I got the project done perfectly without LMs. Datashfet I tried a non inverting amplifier but that didn’t work too. 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.

However I can answer the main question and give a suggestion for datasheett possible cause of your problem: No idea what you are doing. Where do you see the difference now? Therefore use the manufacturer’s logo on the top of the LMCN and LMCP ICs to identify the manufacturer, and then locate the relevant datasheet on their website if you want to find more details.

However I can answer the main question and give a suggestion for a possible cause of your problem:. Do these last letters N and P mean anything like p type or n type? Olin Lathrop k 30 But my guess is that they are electrically identical.

I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor. 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.
