1. Features of LTspice
1. Free
2. Power supply fast simulation
3. Covers a large number of ADI product models
2. How to obtain
LTspice Information Center | Analog Devices
As shown in the figure below, depending on the operating system, download the corresponding installation package and install it.
The software opening interface is as shown below:
3. Run the demonstration circuit
1. Official website download
LTspice® Demonstration Circuit | Design Resources | Analog Devices (analog.com)
2. Run the simulation
Download any demo circuit, the browser will download an .asc file, double-click to open it, and then run it. Click on a signal, such as output voltage, in the circuit diagram below, and the waveform diagram will appear above.
4. Self-drawn circuit
If you draw the circuit yourself, you can select the components in the navigation bar above. If you don't have the component you want, you can find it in Edit, Component.
For example, enter V to find the voltage source.
You can also right-click directly in the circuit diagram and select Component.
After drawing the circuit, you can run it directly.
5. Key points of operation
1. Set the simulation duration
There is a .tran below the circuit diagram. You can set the simulation time by right-clicking it.
2. Modify component parameters
For the component whose parameters need to be modified, right-click to modify it.
3. Modify the Y-axis height
Right-click the Y-axis area to modify it.
4. Enlarge the waveform diagram
Left-click to select a part of the waveform to enlarge it for viewing.
