AD8428 SPICE model not working

Hi all,

I have recently tried to run a simple simulation of the AD8428. I have downloaded the model, imported into LTSpice and run a simple transient simulation. The problem here is that the output does not amplify the input signal, but it stays constant at 5V. 

The Vcc in the schematic is 15V and the input signal is a 10uA 10Hz sine wave through a 10ohms resistor.

I have tried using a symmetrical supply (+-15V) but it still got the same result.

I feel like I'm missing something obvious. Can someone point out in case I'm forgetting something, or help out on suggestions on what to do to get the SPICE model to work?

Thanks in advance.
