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. Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.
op amp – Difference between LMCP and LMCN? – Electrical Engineering Stack Exchange
Please clarify your specific problem or add additional details to highlight exactly what lm741jj need. It is an audio power amplifier.
So I tried creating a basic inverting amplifier using this Adtasheet and the oscilloscope showed the same input signal like waveform as the output signal. But my guess is that they are electrically identical.
That fact that one heats dahasheet and the other works suggests the pinouts are different. Same input lm741u as the output. Do these last letters N and P mean anything like lm741 type or n type? 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: Was just wondering why CN didn’t work when CP did.
Olin Lathrop k 30 The project description was to create a background. 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: Accepted answer provided a better insight!
Just to let you know, this description of your project doesn’t make sense e. Where do you see the difference now?
Just asked this q to get to know what this N and P are! Some other shop sells CP and they work. Yes, post a circuit.
Somehow I got the project done perfectly without LMs. What is the RS, then?
They sell only CNs. The LM is not an op amp. 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. 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.
Depending where your shop sourced the components, then these are some of the possibilities you should consider. LMC ICs sourced from the shop did not work. When I google, for both ICs, it’s the same datasheet.
Here I’ve added the circuit diagram I used to create the inverting amplifier.
