![]() ![]() While the cursor has the shape of a component, it is possible to rotate it using the key combination Ctrl+R (see the hint in the bottom status bar of the main window). Select there the voltage component - this is the power supply, put it on the schematic in two places - click there twice - above and below of the op-amp: Now again press F2 key and in the component selection window go to the root directory. Now click somewhere on the schematic, in a place you want to put the opamp:Īfter the opamp is placed on the schematic, press ESC key to quit the current component selection mode. Press the key F2, it will show the window that allows you to choose a component, then select (use double click), and choose an op-amp you want, in this example we will use LT1013: Example: how to create an op-amp based relaxation oscillator. F6 - Duplicate (Copy a section of a schematic) Īll this functions also accessible via the Edit menu.F2 - place a new component on the schematic.S - place a SPICE directive on the schematic.G - place a GND symbol on the schematic.D - place a new Diode on the schematic.L - place a new Inductor on the schematic.C - place a new Capacitor on the schematic.R - place a new Resistor on the schematic.Now you have to create a new schematic file (from menu File -> New schematic), it will activate almost all icons in the top toolbar:Īpart from icons in the top toolbar, there is some useful function keys: (registration required)Īfter install, click on the program icon and you'll see the main program window: Additional libraries can be downloaded from here and here. There is one very interesting feature in this program - the result of simulation can be written into a wav file, so you can play this file to hear the result.ĭownload LTspice IV here: or here (a direct link): LTspiceIV.exe (15 MB). The system is totally free, it can work in Windows, Mac OS X or Linux using Wine. LTspice IV is a very simple and accurate tool to provide circuit simulation.
