TINA/Spice/THS4503: Cannot Simulate

Cannot get this working??

Steven,
What is the FDA circuit supposed to do?

Hi John,

It is a 40Khz CF Band Pass filter with high gain to detect signals from an ultrasonic sensor.

It is a circuit I borrowed from here:

e2e.ti.com/.../194971

I am new to Tina so it may also have something to do with simulation problems however other designs I have tried seem to run as expected.

Thanks,

Steve

Thanks Steven.
There is something weird going on and will have more to say on that in a day or two.

One thing to note is the simulation circuit is running at 3.3V, but the real THS4503 has a recommended minimum power supply voltage of 4.5V. Models may not cover all behaviors outside of the recommended power supply range so it's not clear if the an actual circuit will work as desired.

Filter_3.TSCThanks John

I also tried a design from FilterPro and have the same issue.
