Do these last letters N and P mean anything like p type or n type? 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.

Home Questions Tags Users Unanswered. Same input signal as the output. 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 dataseet a photo transistor. In this context, no.

I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption.

Is it an analog circuit? It is an audio power amplifier.

The LM is not an op amp. Just to let you know, this description of your project doesn’t make sense e. If this question can be reworded to fit the rules in the help centerplease edit the question. They sell only CNs.

LMJ Datasheet, PDF – Alldatasheet

Accepted answer provided a better insight! Some other shop sells CP and they work. Somehow I got the project done perfectly without LMs. That fact that one heats up and the other works suggests the pinouts are different. LMC ICs sourced from the shop did not work. Blogger 1 The project description was to create a background. Just asked this q to get to know what this N and P are! Shops can get datzsheet batches of components, or perhaps counterfeit etc.

But my guess is that they are electrically identical. By using our site, you acknowledge that you have read datahseet understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Where do you see the difference now? 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. Unfortunately some parts of your project are unclear. 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.


Was just wondering why CN didn’t work when CP did. 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.

No idea what you are doing. Can’t figure out what you are talking about. Please clarify your specific problem or add additional details to datasheet exactly what you need. 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.
