Hi, I am using multisim12. In my project, I am going to use LM399 precision reference. But there is no component in multisim. I want to know how could I solve this, thank you. I am a rookie to multisim12.
With Multisim you have the capability to create your own component. You can follow the steps in the tutorial; Creating a Custom Component in NI Multisim.
You will require the SPICE model, which you can find from the manufacturer's website. You may to contact the manufacturer, if the SPICE model is not available online.
