Hi Hoang Dao,
The AD8182 does not have a spice model yet. But for simulation purposes, you can use the spice model of AD8170 attached. It has almost same specs and performance with AD8182, the difference is that it is a single 2:1 Mux, 250 MHz Bandwidth (-3 dB), and 1000 V/us Slew Rate.
Let me know if you need anything else.
Best Regards,
May
