Hi Matthew,

take the SPice model which you can find here:

https://www.ti.com/product/INA381#design-tools-simulation

and import it into LTSpice as explained here:

Hey Matthew,

Thanks for posting to the forum. The model netlist (which can be copied from the INA381.lib file) will need to be imported into LTSpice to create the model for this simulator as described by Kai.

Sincerely,

Peter
