I’m sorry for mocking you but please say so in your profile or else people won’t make any allowances for you. 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. Started by chemelec Today at 4: Had you searched that, you would have realized that electrics still use 7741cn same kind of receivers as gas models, and use ESC’s, not custom homemade amplifiers to drive the motor Is it 741vn analog circuit?

Where do you see the 714cn now? Somehow I got the project done perfectly without LMs. No idea what you are doing. I wish I could 741c of a good analogy to make it easier to understand, but nothing good comes to mind, maybe someone else can think of something. Started by rashan shrestha Today at 9: Blogger 1 Ebay and similar sources outside the official manufacturer’s 741ccn chain, 741n a higher chance of counterfeit components.

So the 741n could also be described as most? 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. Hero im sory if im not clear english isnt my first language. Since you are planning to use batteries a floating power source it might be possible to come up with some circuit that would do this kind of “addition” to the original input voltage that you seem to want, however I think it would be a pretty poor design with different grounds, and probably not a good idea for a beginner to tinker 741xn, because it would almost certainly be more complex to build and debug than the incredibly simple non-inverting amplifier configuration.

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. Other packaging type letters are also used, but these can all vary between manufacturers. The output can’t “add” to the input voltage in the way you are thinking, because that would imply that the ground reference of the output was the input voltage, which it’s not.

That fact that one heats up and the other works suggests the pinouts are different. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Carefully read the datasheet and understand its limitations. LMC ICs sourced from the shop did not work. Home Questions Tags Users Unanswered. In this context, no. The N and P suffix are packaging; the internal circuit will be equivalent in both parts.

Hero Banned May 27, Unfortunately some parts of your project are unclear. Hero Banned May 25, Can’t figure out what you are talking about. Do these last letters N and P mean anything like p type or n type? With most ESC’s, you plug in a main large battery to the ESC, the ESC has a wire which supplies power to your receiver which no longer requires its own batteryand has another wire that plugs into the receiver in place of the throttle servo that would have been in your gas model, and then of course the motor is connected to the ESC.

Thread starter atntias Start date May 25, If this question can be reworded to fit the rules in the help centerplease edit the question. Looking carefully at the sequence of events, there seems a possible cause.

LM 741CN Amplifier

Click here to register now. They sell only CNs. It is an audio power amplifier.

When I google, for both ICs, it’s the same datasheet. If you want to have batteries powering this amplifier, you’ll need two batteries or 2 sets of batteries to get each the positive and negative supply voltage rails, which could be a lot of batteries 20 or so, if you’re using AA’s.

Just asked this q to get to know what this N 741ccn P are! Why can’t they just answer the question asked in the heading? Shops can get faulty batches of components, or perhaps counterfeit etc. The receiver on the car should output a servo pulse? Addition to that, the IC seems to be heating up a lot.

Again, your “additive” amplifier idea would be even LESS realistic in this situation Yes, post a circuit. Same input signal as the output. Depending where your shop sourced the components, then these are some of the possibilities you should consider.
