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 simulation.
This 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.
LT spice is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. LTspice for Windows PC provides macromodels for most of Analog Devices’ switching regulators, linear regulators, amplifiers, as well as a library of devices for general circuit simulation. Selected Analog Devices devices also have demonstration circuits available for free download. These demo circuits are designed to ensure proper performance and have been reviewed by Analog Devices’ factory applications group. Follow the instructions below to run the demo circuits in LTspice.
