Ad8610 Spice model

Is there an issue with the AD8610 spice model?

When I compare the ADA4610, AD8625 and AD8610, the output (Vout3) of the 8610 is heavily dependent on the input resistor R14.

For 1K or higher the output goes to the -rail.

This occurs when using +- 10V rails (as the design will be implemented)

If i change the rails in the model to +-13V the problem does not occur.

Thanks
