Part Number: LM8261

Hi,

I want to make a noise simulation with the LM8261, but it looks, that input noise isn't included in the model.

Best regards

Hello Bernd,

I've attached a tina circuit that contains a voltage noise block on the input of LM8261. Please let me know if this is sufficient for your simulation purposes.

Best,
Jerry

Hi Jerry,

thanks perfekt!

Can you please check if I atteched it correctly for a "Voltage Follower"?
What about the current noise "i_n", is this included too?

Best regards

Bernd,

What I have provided does not include current noise. A comprehensive guide on creating an accurate noise model is available in the TI Precision Labs videos. I have linked the relevant video below, please note the TINA circuits are available for download further down the page.
