How to add to librrary proteus 8.17 lm339?

Hello Rezamoss

Thank you for reaching out.

Our Proteus models are supported in Proteus 8.9 and later. You may still try importing the model into Proteus 8.17, but please note that our officially supported format is Proteus 8.9 and newer.

Please refer to the Proteus import guide below:

Kindly follow the steps outlined in the guide, and let me know if you have any further questions. We are always happy to assist.

Best Regards
Amina
