LM339 Spice Model .

[hayowazzup]

Hi, does anyone know where I can find Dual supply LM399 spice model? I tried looking it up but could only find the single supply version.
Your help will be greatly appreciated.

It shouldn't matter if you want to use it unipolar or bipolar. Just connect the power-supply terminals correctly.

Thanks a lot man! When I downloaded the model file from TI, all I got was a binary file, which LTspice could obviously not read!
