Was just wondering why CN didn’t work when CP did. Unfortunately some parts of your project are unclear.

LMJ datasheet, Pinout ,application circuits Operational Amplifier

The project description was to create a background. However I can answer the main question and give a suggestion for a possible cause of your problem:. Just to let you know, this description of your project doesn’t make sense e. Looking carefully at the sequence of events, there seems a possible cause.

The LM is not an op amp. Why datasheft they just answer the question asked in the heading? Yes, post a circuit.

That fact that one heats up and the other works suggests the pinouts are different. But my guess is that they are electrically identical. Other packaging type letters are also used, but these can all vary between manufacturers.

The N and P suffix are packaging; the internal circuit will be equivalent in both parts. Same input signal as the output. 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. 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 I tried creating a basic inverting amplifier using this IC and the oscilloscope showed the same input signal like waveform as the output signal. Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.

Accepted answer provided a better insight! Please clarify your specific problem or add additional details to highlight exactly what you need. When I google, for both ICs, it’s the same datasheet. Do these last letters N and P mean anything like p type or n type?

Shops can get faulty batches of components, or perhaps counterfeit etc. 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. No idea what you are doing.

It is an audio power amplifier. Somehow I got the project done perfectly without LMs. 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: I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption.

Operational Amplifier

Just asked this q to get to know what this N and P are! Can’t figure out what you are talking about. In this context, no. Where do you see the difference now? Blogger 1 Don’t use it like an op amp. However I can answer the main question and give a suggestion for a possible cause of your problem: Home Questions Tags Users Unanswered. Here I’ve added the circuit diagram I used to create the inverting amplifier. They sell only CNs. I assumed that it’s not possible for 6 chips to be burnt like that.


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. 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.

LMC ICs sourced from the shop did not work.

Some other shop sells CP and they work. What is the RS, then?

Addition to that, the IC seems to fatasheet heating up a lot. Then I tried a non inverting amplifier but that didn’t work too. See the How to Ask page for help clarifying this question. Depending where your shop sourced the components, then these are some of the possibilities you should consider. I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor.

So the difference could also be described as most?
