struggling with Spice simulation of AD8513

Hi

I want to use AD8513 with my circuit but first I want to simulate its behavior, My design software is Altium Designer, after spending time on it try trying to figure out why it doesn't behave correctly I realize I may not inserted correctly the Spice model of AD8513, I did try to open the model in LTspice and I think I figure my problem with it's. I think the cause of my problem is that the Spice model for the AD8513 works only for 1 OpAmp inside it, I got that conclusion because after adding that Spice file to LTspice it created only one OpAmp and not 4 as I was wanted.
If I'm correct, Whats are my options to simulate all the 4's OpAmps of this component?

  • Hi d.shpigel,

    Moving to the LTspice Q&A.

    When you add an AD8513 to an LTspice schematic, it is true only one amplifier out of 4 is added at a time, just add four total gates. Of course you will need to power all four from the same rails.

    Are you seen an issue when trying to run a simulation that includes more than one individual AD5513 amplifier? If so, can you post a schematic that shows the error?
