pmw fan controllers

asked around a bit and this is the response i got concerning multiple taps off of any signal wire:

That's called "fanout" and yes, it is a concern in digital circuits as well. Ideally you'd check the datasheet for the component, but that might not be an easy option with proprietary or obfuscated hardware.



If you at least know the impedance of the device you are attaching, you could make an educated guess. But the best solution (that i can think of) would be to use a jfet op-amp in voltage-follower configuration as a buffer.

Thanks for the info. Not that a lick of it makes any sense to me, but the effort is appreciated nonetheless :-)
