INA293: Weird glitch on the output as soon as input rises

Hello Lauren,

Please make sure that the bias point is calculated.  It is a selection in the simulation profile to calculate the bias point.  If it is still an issue attempt to change the transient step size.  Please forward me the simulation if this does not fix the issue.

Please be aware of two items with the INA293.  The Bandwidth vs Vsense (Section 7.3.1.1)and overload recovery(Section 8.2.2.1) covered in the datasheet.  The model does not support these behaviors.  

In Tina if you calculate bias point it works.  I may have the correct bias point in my simulation.   I found the root cause.  If the device starts in a condition what would be considered a saturation point  (Swing Low ) in this case the model seems to have trouble getting out of this mode.  One way to avoid it is to bias it initially above the saturation point somewhere in the linear range. 

I will look to see if there is a simple way to fix this in the model, but this will take some time to investigate an alternative way to implement the saturation in the model.
