Soal toeic dengan kunci jawaban. Attached are the two files you need for LTspice. I modified an appropriate LTspice.asy symbol file to access the 1N2128.lib file.

Put the.lib file in C: Program Files (x86) LTC LTspiceIV lib subdirectory. Put the.asy file in C: Program Files (x86) LTC LTspiceIV lib sym Opamps directory Make a backup copy of both those directories first. Close and open LTspice to make the new device available.

Here's a demo of the IC for a gain of six: Edited 4/12/17 to correct error in the symbol modification explanation. Added dummy pins were not needed.

As it is spoken: do not let's him fish, but give fishing rod! HELP Automatic Symbol Generation A symbol can be automatically generated in two situations. When editing a schematic, you can execute menu item Hierarchy=Open this Sheet's Symbol. When no symbol is found, LTspice will ask if you would like one automatically generated. This symbol then can be used to call this sheet of circuitry in some higher level schematic. Also, when editing an ASCII netlist that contains subcircuit definitions, you place the cursor on the line containing the name of the subcircuit, right click, and execute context menu item 'Create Symbol.' For most users, this is the only method you should consider for adding third-party models defined as subcircuits since all the details are handled for you.

My approach is to find a schematic symbol.asy file in the C: Program Files (x86) LTC LTspiceIV lib sym directories and then click to edit it in the LTspice editor, changing it to match the.lib file you have. Here's an example symbol in the edit window: Right-click on each pin to edit it's name and netlist number. The number must correspond to the netlist connections in the.lib/.sub file as shown here: The symbol netlist number corresponds to the position of the connections in the.lib/.sub file starting with number 1 on the left. Thus, for example, symbol Netlist pin 3 corresponds to node 99 in the LM324.lib file. You also go to the Symbol Attribute Editor to add the.lib/.sub file it should connect to as well as the part designation and description: When you've make the needed changes you do a Save As with he new symbol name corresponding to the IC designation. The.lib/.sub files go in the C: Program Files (x86) LTC LTspiceIV lib sub directory.

The.asy file goes in the appropriate C: Program Files (x86) LTC LTspiceIV lib sym directory. Note that most standard.lib Spice files will work but some use unique characters or designations that will give an error and you may have to do some sleuthing to correct the problem.
