Hi
Has anyone measured the noise of the LND150, or created whatever noise-related spec goes into a spice model for LTspice?
The manufacturer primarily describes it as a high-voltage switch or lamp ballast device, and ... oh yeh... it can be used in linear applications. Being a mosfet, I expect it to be ten times noisier than an average n-jfet, but some real data would be nice to have.
Thanks 🙂

Hi nauta,
I use them for current sources all the time. Sometimes several hundred voltage drop. I haven't noticed any excessive noise and i often use them in diff pair type front ends as tail current sources.
A J-Fet often doesn't have the voltage compliance I need. They seem to be pretty stable at the set current as well.
