The N and P suffix are packaging; the internal circuit will be equivalent in both parts.

Blogger 1 Home Questions Tags Users Unanswered. Olin Lathrop k 30 I assumed that it’s not pm741j 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.

However I can answer the main question and give a suggestion for a possible cause of your problem: Is it an analog circuit? Can’t figure out what you are talking about. The LM is not an op amp.

It is an audio power amplifier. What is the RS, then? 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?

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. I’m having an analog project where I have to amplify satasheet weak signal coming out of a photo transistor. Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.

See the How to Ask page for help clarifying this question. When I google, for both ICs, it’s the same datasheet.

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

Then I tried a non inverting amplifier but that didn’t work too. Just asked this q to get to know what this N and P are! Don’t use it like an op amp. LMC ICs sourced from the shop did not work. Looking carefully at the sequence of events, there seems a possible cause.

Depending where your shop sourced the vatasheet, then these are some of the possibilities you should consider. Somehow I datashret the project done perfectly without LMs. I assumed that it’s not possible for 6 chips to be burnt like that.

Was just wondering why CN didn’t work when CP did. 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. If this question can be reworded to fit the rules in the help centerplease edit the question.

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. Addition to that, the IC seems to be heating up a lot. Accepted answer provided a better insight!

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: 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.

vatasheet 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:. Same input signal as the output.
