ADA8282 SPICE model failure

I've simulated this:

In LTspice but it behave weird I can't understand my fault, I think maybe the model have problem?
I've downloaded the model from ADA8282 ADI page.

Also I've followed it's evaluation board approach UG-846:

still the problem exist.

New question rises: why they've used C5, R5 and R4? 

New information added.

  • Hi mohammadsdtmnd,

    I think you are asking about the source E1 in my schematic?

    That's just a "voltage dependent voltage source" to help me create the differential input by specifying its gain to be "-1V/V" so that it'd be inverted compared to the other source V1.

    I'll forward the question about the misbehavior of ADA8282 pspice time-domain transient response issue going past 45ms to people in charge and if I get a resolution I'll post it here.
