Multiple ADA2200 demodulating LVDTs, How to drive the primaries?

Hello all,

I am using the reference design in as described in CN0371 where in an ADA2200 is driving an ADG794 switch. The the reference has 2 of the four outputs of the switch dedicated to driving P+ and 2 dedicated to P-.

So here is my question: I need to drive 8 LVDTs, can i drive them from the one switch with the primary coils in parallel or have a dedicated switch for each LVDT?

Thanks in advance,

-Erik
