LMH6611: Convergence problems when the amplifier is simulated in pspice for TI.

Part Number: LMH6611
Other Parts Discussed in Thread: OPA810, TINA-TI

I want to simulate a circuit which is showed in the TI's document :SLUUC92. The amplifier LMH6611 and mosfet SIS412DN-T1-GE3 are used by the circuit.

But when I simulate this circuit with pspice for TI, the convergence problem happens.

When I use another amplifier OPA810,the circuit can be correctly simulated.Hence I detect that there is something wrong with the model of LMH6611.Therefore, I omly use the LMH6611 to simulate a follower circuit:

But the convergence problems still occurs.What's the reason of the mistake?

Thanks!
