To import a simple third party SPICE model into LTspice using the.MODEL directive, follow these steps: Add a generic component to the schematic that represents the symbol of the SPICE model. Download the SPICE model into the same directory as the circuit you are simulating. The selection includes over 200 op amp models, resistors, transistors, and MOSFET models. Our software library provides a free download of LTspice IV 4.15. The most popular versions of the program are 4.1 and 4.0. LTspice IV lies within Photo & Graphics Tools, more precisely 3D Design. LTspice is a high performance SPICE simulation program app, schematic capture and waveform viewer with enhancements and models for easing the simulation of analog circuits. Included in the download of LTspice are macromodels for a majority of Analog Devices switching regulators, amplifiers, as well as a library of devices for general circuit.

Introduction
Download Ltspice Models 2017
LTspice is a free SPICE simulation software tool with schematic capture, waveform viewer, and many enhancements that runs on both Windows and Mac OS X. I use it to research circuit behavior and quickly experiment with new circuits for my lab before prototyping a PCB (Printed Circuit Board) design. The learning curve is easy to conquer thanks to support by Analog Devices, Yahoo's LTspice Support Group and its compatibility with most common SPICE models supplied by chip vendors.
This Instructable will demonstrate 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.

The target audience are those with some experience placing components on a schematic and running a simulation. By the end of this tutorial you will know how to interpret the .SUBCKT command within manufacturer models for use with LTspice's opamp2 Pin Table and Attribute editors to use manufacturer parts within your simulations.
