ADA4350 SWA_OUT and SWB_OUT of SPICE MODEL

Hi Guys, 

It seems that the connection between SWA and SWB of SPICE MODEL(ADA4350.cir) is reversed.

Could you please check it?

    Hi Yuki,

    Yup! It seems that the S6, S7, and S8 should be connected to node 27 and S9, S10, and S11 should be connected to node 1. Here's the updated version:
