So I tried creating a basic inverting amplifier using this IC and the oscilloscope showed the same input signal like dahasheet as the output signal. Addition to that, the IC seems to be heating up a lot. Then I tried a non inverting amplifier but that didn’t work too. Same input signal as the output.

I assumed that it’s not possible for 6 xatasheet to be burnt like that One of my friends had a LMCP IC and I plugged ddatasheet the same proto board with the same pin configuration and it worked. Do these last letters N and P mean anything like p type or n type? Here I’ve added the circuit diagram I used to create the inverting amplifier. The project description was to create a background.

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

Please clarify your specific problem or add additional details to highlight exactly what you need. See the How to Ask page for help clarifying datadheet question. If this question can be reworded to fit the rules in the help centerplease edit the question. Unfortunately some parts of your project are unclear. However I datwsheet 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. I assumed that it’s not possible for 6 chips to be burnt like that. Shops can get faulty batches of components, or perhaps counterfeit etc. Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.

Depending where your shop sourced the components, then these datassheet some of the possibilities you should consider.

Operational Amplifier

In this context, no. Other packaging type letters are also used, but these can all vary between manufacturers. Therefore use the manufacturer’s logo on the top of the LMCN and Datashee ICs to identify the manufacturer, and then locate the relevant datasheet on their website if you want to find more details. Looking carefully at the sequence of events, there seems a possible cause. So the difference could also be described as most? LMC ICs sourced from the shop did not work.

Where do you see the difference now?

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. Carefully read the datasheet and understand its limitations. Home Questions Tags Users Unanswered. Blogger 1 The N and P suffix are packaging; the internal circuit will be equivalent in both parts.

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.


But my guess is that they are electrically identical. 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. Yes, post a circuit. No idea what you are doing.

Is it an analog circuit?

What is the RS, then? Can’t figure out dtaasheet you are talking about. The LM is not an op amp. It is an audio power amplifier.

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: I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption. 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: Why can’t they just answer the question asked in the heading?

They sell only CNs. Some other shop sells CP and they work. Dataheet I got the project done perfectly without LMs. Just asked this q to get to know what this N and P are!

That fact that one heats up and the other works suggests the pinouts are different. Olin Lathrop k 30 When I google, for both ICs, it’s the same datasheet. Accepted answer provided a better insight!
