OK... what the... im completely confused now!
refin =/across 1-200%is at 1.23v vs 1.25v = r1-r4 within r2.
ok so i may not be as bad as that.. but im sitting here looking at the thing thinking.. wtf. it doesnt make any sense to me at all. i mean, it does, but it doesnt. and ... can someone just explain to me how on earth this all works?
I understand that the. im rather new to anything that has more than 2 legs. like honestly, i've only just started playing with transistors and using transistors!
how does one take a 2.5v - 11.8v adjusted voltage and turn it into a 0-1.25v signal.
im getting more and more grey hair here. is it simple and im just not getting it or is it really complex for a simple minded person like me.
The was my plan before started geting confused and bleeding from the ears.
I have a PC here thats a server, i've made the CPU fan run on around 5v, which is keeping it nice and cool, what i wanted to do is have to graphs, bar or dot, that part i do get! but basically one graph was going to tell me what the voltage is out from the fan speed controller, and the other was going to be the temp from the CPU.
SO that where i get stuck. well wait no i dont, i dont know where i get stuck, my brain just cant wrap my head around the IC.. its ticking me off...
