Single supply multiplexers to switch analog signals ranging from -1V to +1V

Hello Rami,

Thanks for the reply.

You suggested a SPST Mux but i require a SPDT switch and it has more on resistance. Pricing is not an issue but signal should not degrade or attenuate .

Is there any Mux that can handles -/+300mV analog signal range and can work with single supply?

Thank You,

Veera.

Hey Veera,

Sorry I wasn't so clear there. Yes, it's a SPST due to the limitations in our options but my recommendation meant to add that you'll need to tie the outputs together as needed to create your SPDT (Although I was under the impression you needed to mux 8 signals, so an 8:1 mux)

So here are our devices that can support a negative voltage with a single supply:

Unfortunately you'll notice that none actually support up to 350MHz though so we won't have something that fits that requirement. 
Which is why I would recommend to use a second supply here to open up our options. If that isn't an option though, we currently don't have anything to meet that need.

Thanks,
Rami

Hello Rami,

So, you are suggesting me to use Dual supply in my design and currently i am using buck converter of 5V. is there any IC available that will work +5v and -5V parallelly with 1 to 2A current  sourcing.

Please suggest a 500 Mhz SPDT mux with low RON and COn . Dual supply also fine .
