How to Use a Chip Vendor Op-Amp Model in LTSpice

I introduce an Instructable that demonstrates how to go beyond the component library supplied with LTspice by incorporating an LMV321 op-amp model from three different chip vendors to create a simple amplifier schematic as shown in the drawing. Each of these models highlight different methods available within LTspice for use with the wide variety of component models supplied from various vendor websites. Each of these models present different performance features as well. To highlight these performance issues I reuse these three models in a Current-to-Voltage design as well.
