LTspice® is a high performance SPICE simulation software, 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 simulation.

Benefits of using LTspice

Our enhancements to SPICE have made simulating switching regulators extremely fast compared to normal SPICE simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. This video provides an overview of the advantages of using LTspice in an analog circuit design and how easy it is to get started.
The key to most circuit designs is the speed with which you can reach an understanding of your circuit, its correctness, and its limitations, so that you can refine your design and select components before going into the lab to prototype and test. LTspice® is Analog Devices’ high performance circuit simulation program, which allows you to draft, probe, and analyze the performance of your circuit design. LTspice contains an integrated schematic editor, waveform viewer, and advanced features that are easy to use once you learn some basic commands.

LTspice includes an extensive library of macromodels covering most of ADI’s power management and signal chain products, as well as a library of passive components. LTspice uses proprietary modeling techniques for its macromodels, resulting in fast, accurate simulation results.1 This is especially important for switch-mode power supply designs, an area where LTspice outperforms many other simulation tools and enables you to iterate your designs in minimal time. Successive simulations allow you to explore the circuit limitations and performance boundaries of your design through minor adjustments, helping to develop your circuit intuition.

LTspice is provided at no cost to our customers and to the engineering community.* Do not let its free status dissuade you; it outperforms many simulation solutions in the market and is not hobbled by any arbitrary limits. Consequently, you can create, encapsulate, and abstract complex circuits with confidence that circuit size and hierarchy are only limited by your computer’s resources and your time.
