Was just wondering why CN didn’t work when CP did. Same input signal as the output.

LMJ Datasheet pdf – Operational Amplifier – National Semiconductor

Why can’t they just answer the question asked in the heading? LMC ICs sourced from the shop did not work. I’m having an analog project where I have to amplify a weak signal coming out of a photo transistor. I assumed that it’s not possible for 6 chips to be burnt like that ,m741j assumption. By using our site, you acknowledge that you have read datashheet understand our Cookie PolicyPrivacy Policyand our Terms of Service. Somehow I got the project done perfectly without LMs.

Can’t figure out what you are talking about.

But my guess is that they are electrically identical. Is it an analog circuit? See the How to Ask page for help clarifying this question. They sell only CNs. Home Questions Tags Users Unanswered.

Carefully read the datasheet and understand its limitations.

The LM is not an op amp. Looking carefully at the sequence of events, there seems a possible cause. Dahasheet I tried a non inverting amplifier but that didn’t work too. Do these last letters N and P mean anything like p type or n type? It is an ml741j power amplifier. Addition to that, the IC seems to be heating up a lot. If this question can be reworded to fit the rules in the help centerplease edit the question.


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.

Just to let you know, this description of your project doesn’t make sense e. 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 darasheet which made people drove outta their minds: Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.

We can only help when sufficient information is presented; draw a circuit diagram datashwet the small circuit widget in the edit controls will open a schematic editor. What is the RS, dtaasheet That fact that one heats up and the other works suggests the pinouts are different. Yes, post a circuit.

Operational Amplifier

When Datasheeet google, for both ICs, it’s the same datasheet. 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. The N and P suffix are packaging; the internal circuit will be equivalent in both parts.


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.

Olin Lathrop k 30 However I can answer the main question and give a suggestion for a possible cause of your problem: Depending where your shop sourced the components, then these are some of the possibilities you should consider.

Where do you see the difference now? No idea what you are doing. Datashfet packaging type letters are also used, but these can all vary between manufacturers.

So the difference could also be described as most? However I can answer the main question and give a suggestion for a possible cause of your problem:. Blogger 1 The project description was to create a background. Please clarify your specific problem or add additional details to highlight exactly what you need. Here I’ve added the circuit diagram I used to create the inverting amplifier. Some other shop sells CP and they work. In this context, no.

Shops can get faulty batches of components, or perhaps counterfeit etc.

I assumed that it’s not possible for 6 chips to be burnt like that. Also the is ancient Datashheet better use a TL or TL, even those are old but much more suited to many of today’s applications.
