Hi,

I looked through our model database and unfortunately, we do not have a model for these devices.

Best Regards,

Actually, I only need to simulate the 'amplifier' part, the 'mux' part is not so important. Are there a sim model from a similar CFA that I can use?

Thanks.

Hi,

I went through our CFA portfolio, and I did not see a direct match to the specs of the mux device. The closest one I was able to find was the LMH6703. However, I am not sure this would reflect this device all that well. For better estimates on the performance of this device, the datasheet information would probably provide a more accurate picture for you compared to a CFA model of a different device.

Best Regards,

Ignacio

Hi,

I find someone used a model of 4872 in his simulation, in OPA4872: OPA4872: OPA4872 50R termination causes distorted input - Amplifiers forum - Amplifiers - TI E2E support forums. So it seems indeed a model exist or existed.

Hi,

That is a good catch. I was able to look through a different repository and found the .lib file for this device. I still could not find the LMH6574. However, it seems like E2E is having some issues as I cannot attach any files. I went ahead and sent you a friend request so I can send the file through there.

Best Regards,
