Hi there,


Our customer is attempting to use the AD8139 Spice model in an Altium simulation. 


They have found that the model is not working correctly and the behaviour of the model is such that it appears that one of the inputs is not connected properly.  When they replace the AD8139 model with the AD8138 model, they are able to simulate their design without issue.  Can someone at ADI review the AD8139 model and advise?


Kind regards,
