Hello,

I need to use a multiplexer to select various power lines. I searched online and found many but the datasheets confused me a bit.
There's called Ron and Ron flatness what exactly is the difference between the two? I need one with as little resistance as possible. Also something about the current output, I want to be able to pass from very little current (~nA) all the way to 2A. What sort of specification should I look for in the data sheet?

Thanks!

 

Power lines are 230 VAC or what?

Can't you tell us what you are up to? nA to 2 A seems extreme, I'd say.

 

I don't remember any multiplexers that can handle 2 amps. Can you post a part number and its datasheet? I suspect you are going to wind up with the multiplexer commanding other devices to handle that much current.

 

Ron changes with voltage applied, so the Ron flatness describes by how much it will vary.
