Olin Lathrop k 30 Home Questions Tags Users Unanswered. They sell only CNs. Why can’t they just answer the question asked in the heading? Don’t use it like an op amp. Accepted answer provided a better insight! Please clarify your specific problem or add additional details to highlight exactly what you need.

Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components. 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. However I can answer the main question and give a suggestion for a possible cause of your problem:. Carefully read the datasheet and understand its limitations.

Yes, post a circuit. The project description was to create a background. Here I’ve added the circuit diagram I used to create the inverting amplifier. 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. Other packaging type letters are also used, but these can all vary between manufacturers. Also the is ancient You better use a TL or TL, even llm741j are old but much more suited to many of today’s applications.

In this context, no. Do these last letters N and P mean anything like p type or n type? See the How to Ask page for help clarifying this question.

I assumed that it’s not possible for 6 chips to be burnt like that. Depending where your shop sourced the components, datassheet these are some of the possibilities you should consider. Unfortunately some parts of your project are unclear. Is it an analog circuit?

Somehow I got the project done perfectly without LMs. Some other shop sells CP and they work. That fact that one heats up and the other works suggests the pinouts are different.

Can’t figure out what you are talking about. However I can answer the main question and give dagasheet suggestion for a possible cause of your problem: No idea what you are doing. Addition to that, the IC seems to be heating up a lot. It is an audio power amplifier. When I google, for both ICs, it’s the same datasheet. The LM is datashee an op amp.

Then I tried a non inverting amplifier but that didn’t work too.

National Semiconductor

Should have asked ‘What is the difference between letter N and P at the lm741i of LMC’ instead of giving out details of the project to create a background to the question which made people drove outta their minds: Was just wondering why Dataeheet didn’t work when CP did. I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption. So the difference could also be described as most? Where do you see the difference now?

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. LMC ICs sourced from the shop did not work.

What is the RS, then? Same input signal as the output. Shops can get faulty batches of components, or perhaps counterfeit etc. I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor. Looking carefully at the sequence of events, there seems a possible cause. Just to let you know, this description of your project doesn’t make sense e.
