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. Why can’t they just answer the question asked in the heading? However I can answer the main question and give a suggestion for a possible cause of your problem: I dxtasheet that it’s not possible for 6 chips to be burnt like that Wrong assumption.

I assumed that it’s not possible for 6 chips to be burnt like that. Is it an analog circuit?

op amp – Difference between LMCP and LMCN? – Electrical Engineering Stack Exchange

The project description was to create a background. So I tried creating a basic dtaasheet amplifier using this IC and the oscilloscope showed the same input signal like waveform as the output signal. So the difference could also be described as most? 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. Shops can get faulty batches of components, or perhaps counterfeit etc.


Should have asked ‘What is the difference dataasheet letter N and P at the end of LMC’ instead of giving out details of the project to daatasheet a background to the question which made people drove outta their minds: It is an audio power amplifier.

They sell only CNs. Blogger 1 Here I’ve added the circuit diagram I used to create the inverting amplifier.

Do these last letters N and P mean anything like p type or n type? Just asked this q to get to know what this N and P are! But my guess is that they are electrically identical. Don’t use it like an op amp.

The LM is not an op amp. Yes, post a circuit. I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor. Home Questions Tags Users Unanswered. Addition to dayasheet, the IC seems to be heating up a lot.

Operational Amplifier

Looking carefully at the sequence of events, there seems a possible cause. 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. However I can answer the main question and give a suggestion for a possible cause of your problem:. Depending where your shop sourced the components, then these are some of the possibilities you should consider. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Other packaging type letters are also used, but these can all vary between manufacturers. LMC ICs sourced from the shop did not work. Can’t figure out what you are talking about. That fact that one heats up and the other works suggests the pinouts are different. Just to let you know, this description of your project doesn’t make sense e. In this context, no. 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.


Same input signal as the output. Where do you see the difference now? Please clarify your specific problem or add additional details to highlight exactly what you need.

No idea what you are doing. Some other shop sells CP and they work.

Carefully read the datasheet and understand its limitations. Accepted answer provided a better insight! The N and P suffix are packaging; the internal circuit will be equivalent in both parts.

Unfortunately some parts of your project are unclear. Somehow I got the project done perfectly without LMs. When I google, for both ICs, it’s the same datasheet.

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. Ebay ,m741j similar sources outside the official manufacturer’s supply chain, have a higher chance of lm74j components.

If this question can be reworded to fit the rules in the help centerplease edit the question. What is the RS, then?
