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.

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!
