ADG 419: Analog and Digital supply ?

Hello everybody,

I'm studying a new electronic sensor applications. I would use the ADG419 to switch analog signals. The ADG419 will be control by a µC.

Vsupply µC Digital : +3.3V to GND

Vsupply Analog: +5V;-5V;AGND

I would know if my schematic (see the attached file) is correct. In order to delete the noise because of the digital supply (µC), I would to separate the analog and digital supply.

Thanks for your help.

Best regards.
