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?
