Spice model of OP470  /  Problem with the input bias current

Hi,

 

While testing the model of the OP470 Op-Amp which we plan to use on a MIL PCB, I found a problem during the transient analysis.

The datasheet of this component tells us that the input bias current should be around 10nA

But in the simulations I have a short between the / inputs and kilo-amps flowing through them.

 

Joined you have a picture of the setup.

 

Could you help me ?

 

Best regards,

Altay
