Depending where your shop sourced the components, then these are some of the possibilities you should consider. Unfortunately some parts of your project are unclear. No idea what you are doing.

However I can answer the main question and give a suggestion for a possible cause of your problem: So the difference could also be described as most? Olin Lathrop k 30 It is an audio power amplifier. Here I’ve added the circuit diagram I used to create the inverting amplifier. What is the RS, then? Accepted answer provided a better insight! Then I tried a non inverting amplifier but that didn’t work too.

LMC ICs sourced from datasheet shop did not work. Where do you see the difference now? But my guess is that they are electrically identical. Looking carefully at the sequence of events, there seems a possible cause. 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.


National Semiconductor

That fact that one heats up and the other works suggests the pinouts are different. Do these last letters Datadheet and P mean anything like p type or n type? 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 Lmm741j plugged into the same proto board with the same pin configuration and it worked. Shops can get faulty batches of components, or perhaps counterfeit etc. When I google, for both ICs, it’s the same datasheet. See the How to Ask page for help clarifying this question.

Operational 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. Ebay and similar sources outside the official manufacturer’s supply chain, have a higher chance of counterfeit components.

Can’t figure out what you are talking about. However I can answer the main question and give a suggestion for a possible cause of your problem:. Some other shop sells CP and they work. Why can’t they just answer the question asked in the heading?

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 datasheer their website if you want to find more details.

Is it an analog circuit? Yes, post a circuit.

In this context, no. Addition to that, the IC seems to be heating up a lot. Other packaging type letters are also used, but these can all vary between manufacturers.

Home Questions Tags Users Unanswered. Same input signal as the output. The project description was to create a background.

Just asked this q to get to know what this N and P are! I assumed that it’s not possible for 6 chips to be burnt like that Wrong assumption. If this question can be reworded to fit the rules in the help centerplease edit the question.

I assumed that it’s not possible for 6 chips to be burnt like that.
