LMH32404: Wrong noise results from LMH32404 Spice simulation

Part Number: LMH32404

Greetings,

I have conducted a noise simulation for the LMH32404 in LTspice. Please refer to the schematic and results provided below.

The noise results show a significant deviation from the input noise indicated in the datasheet. Is there a potential issue with the Spice model?

Thank you,

Sariel

    Hi Sariel,

    After looking into the macro for this device, it appears this spec was not modeled for this device. For something like this device, we currently do not implement a model architecture that models noise data vs the various specs like the device highlights in the datasheet which is why it was likely not added to the model. 

    Best Regards,

    Ignacio
