AD8138 SPICE Simulation Problem

I am using an AD8138 in a preamplifier design.  The circuit is unity gain with 1100 ohms input and feedback resistors for both positive and negative inputs.  Supplies are +/-5V.  With +input grounded and VCOM grounded I get 40mA of current flowing OUT of the negative supply terminal.  Is there a problem with the spice model.  I downloaded the model from ADI and the header indicates this is REV E created by ADI on 11/2002.  Any ideas?
