Re: Which pin is the ground in this low power dual op-amp " LM358N " ? thanks
so if we put -0.3 V then what would be the output ?
&
if we apply +32v then what would be the output ?
thanks
First of all it is not good to push a device into its limits. Secondly, your question cannot be answered because there is a lack of data. An opamp can be configured in many topologies. So if you have two opamps with the exact same inputs, you could have different output because of the different topology. Then you could have same topology but different inputs, so the result would also change. If you are using feedback, then for same inputs and same topology you could again have different output, because of different feedback.
By following this thread, I concluded that your real question is "how does an opamp work".:smile: It is not bad, I am just telling you this so you can ask questions more effectively next time. There is no point on answering a question and then asking something different and then something different. Also this is against forum rules. Ask exactly what you want to get the exact answer you need. :wink:
Here is a reference to start with.
Operational amplifier - Wikipedia, the free encyclopedia
Read it carefully and if some parts are hard to understand, read it again and again until it gets clear. You can then come back and open a new thread, with a specific question on a part or parts you did not understand.
If you need more references, then google for "opamp", or if you need something specific (like let's say comparator) then google for "opamp comparator". Of course if there is any book available next to you, just open it!!! :-D
