Hi, this is a follow up from http://e2e.ti.com/support/development_tools/webench_design_center/f/234/t/272850.aspx.
I put together a test bench with a TI THS4150 differential driver and an INA146 differential receiver, to experiment with the common mode input range of the INA146.
This might not be the best way to perform the experiment but I connected a 50Hz triangle wave to the reference pin (2) on the TMS4150 and had this go from -20V to +20V.
I wanted to see the INA146 handle this input but with the tranmission line subcircuit described in the post linked above, the 50Hz component was blocked.
Wondering if this is a newbee error on my part or if there is something not quite right about the tranmission line component. I did read in some places that the tranmission line model might be 'behavioral' and act odd so wondering if this is the case.
BTW - I wound up deleting the tranmission line from the circuit and just using 'wires' and I could then see the 50Hz +/-20V component of the input signal on the INA146, and see that it was removed from the output waveform. But would have liked to gottent the tranmission line in there.
Best Regards,
Anthony
