Wait a minute... Simple amplifier question
 

What happens when I amplify voltage 10 000 times? or 100 000 times?

And supply this voltage the to regular Analog IC?

I saw several circuits when they do that without any protection measures?

But how is this possible? If I amplify just 1V 10k times it becomes 10 000V. Without any resistor it is 10 000 Amps!!!!!!!!!!

It can blow up everything to sh"t.

Interesting first post for a RC site. Can you provide more info on what you saw?

If it's a typical op amp for example, just a guess based on your high gain comments, a feedback circuit can lower the gain to an appropriate level for the IC.

Oops
 

I think it takes supply voltage as it's limits?

Am I right?

So if I have +15 and -15 supply it is 30V maximum?

But nevertheless 30V is 30Amps.

It depends, need more info, voltage gains vary based on the circuit. FYI, 30V does not necessarily equal 30 Amps, depends on load.

I drawed some picture, but I cant post link here, since I registered today and created my first post

Thank you Dave, usually I wait days to see any answer regarding electronics)
