Hi Alexsysoev000, Welcome to EasyEDA. Sorry but the ST L165 is an obsolete device: http://www.st.com/content/ccc/resource/technical/document/datasheet/0e/12/98/34/ac/2b/4e/1a/CD00000052.pdf/files/CD00000052.pdf/jcr:content/translations/en.CD00000052.pdf for which no simulation model is available. If you want to simulate it as part of a larger design then probably the simplest thing to do it to replace it by a voltage source or a very much simplified behavioural model. A simplified behavioural model will do very little to model the L165 with any accuracy but it can be run using a schematic symbol so it will look the part in a simulation schematic.

Hey! You're in luck. A careful study of the old TDA2030 datasheet shows that it is *very* similar to the L165: TDA2030 datasheet: http://www.farnell.com/datasheets/1839262.pdf?_ga=1.128155980.172985125.1461855267 L165 datasheet: http://www.st.com/content/ccc/resource/technical/document/datasheet/0e/12/98/34/ac/2b/4e/1a/CD00000052.pdf/files/CD00000052.pdf/jcr:content/translations/en.CD00000052.pdf And guess what? I've already built an EasyEDA spice model for the TDA2030. All you have to do is to replace your L165 symbol with the `5 pin operational amplifier` symbol from the EasyEDA Libs. Then just edit the name from `UA741` to `TDA2030EE` and you're done! The TDA2030EE model does not model the SOA protection of the actual device (TAD2030 or L165) but is reasonably accurate for most other parameters. Look at the .subckt in the netlist to see more about it. Have fun! :)

@andyfierman TY for you unswer!) you help me rlly!
