Choosing a CMOS Switch (ADG1434)

Hello,

I need to switch different signals to an ADC. I already choose the AD7195 for my application.

In the application I need to multiplex a differential input of the ADC (channel AIN1 and AIN2).

I want to use a CMOS switch for that.

Another point is that I have an embedded system supplied by around 12V (9V to 20V in fact).

ADG1434 sound good for my application, but can I supply this part with my supply voltage (9V to 20V)?

Or is a regulated 12V mandatory?

In fact it is not plane to use differential +-5V or +- 15V on the board.
