I want to use the ADG411 +-12V but with a Vlogic=3V - would this work?

 

Yes it is possible to apply 3V to the Vl pin. We just have it specified at 5V.
For the ADG412 the Vl applied can be in the range of -0.3V to Vdd +0.3V.  Our
parts are spec’ed with a Vl of 5V but this can be varied, so 3V is fine.
However your trigger levels will also vary accordingly. The attached pdf file
shows what will typically happen when VL moves away from 5V.
