LMH6503: Single Supply Operation

Part Number: LMH6503

Hi,

Just a question about the LMH6503 and running it in a single supply configuration.  On page 22, figure 65 there is a circuit shown for single supply operation.  When I duplicate this into TINA TI I am not seeing any gain functioning when Vg is tuned.  Seems to run wide open all the time.  Here are some screen shots of what I have in TINA.  I think it is hooked up correctly but something is not right.  Any help?



I run an ac analysis, AC transfer characteristic from 0.99M to 1.01M (TINA doesn't seem to allow single freq anlaysis) and tune Vg from -1 to +1 in 6 steps.  The output is the same at all tuning voltages:




The model works ok when I use bipolar supplies.  What am I doing wrong?
