Hi, I was trying to use the .cir model of the AD8045.

--- By manually adding the library to the simulation profile I was able to make the design recognizing this device.

-- Then, I tried to perform AC simulations, but I got the following error, where X_U1 is the AD8045.

I might need help in fixing this.

Thanks,

Silvia

Looks like a typo or deletion.

Change the line to:

X_U1.CinDiff X_U1.9 X_U1.2 0.1e-12Harry
