Hi,
I need to learn more about building circuits and analyzing them, and since I started learning LTspice recently, I decided to pick a few circuits every week about LTspice from different online available resources and try to understand them/analyze them to help myself learn about circuitry.
So, I've found a lot of circuits online and downloaded a zipped file that has a couple hundreds of .asc circuits. So, I picked the first one in the folder and was called 1563 and when run/simulated this circuit that's what I got:


So:
What is this circuit called? I looked for 1563 ic and found something about dc to dc convertor? Is that what it is, a dc-to-dc converter?
where to find this U1 component in the LTspice?
What is TowTom2?
What does this plot tell me?
circuit is attached

Thanks

 

My best guess:

From the Misc parts file:

So it's a filter as Dick posted.
The 1563 must just be an arbitrary file designation.

Cool, thats very helpful guys! i will go thought he datasheet and come back to you!

 

LT1563

 

LT1563

Duh, of course.

 

So, is this one:


same as this one:



The above one is 2nd order and the below is 4th order.
