Tool/software: TINA-TI or Spice Models
I use TI parts in many of my designs, but for this case I am trying to determine why I am getting unexpected results for a non-TI part, the ADA4841. I am concerned that I am setting up something wrong in TINA-TI, since this is my first time using an imported macro model.
I have imported the model and created the following circuit.
At 10kHz and higher, SIG2 (red) is no longer fully tracking SIG1. The model seems to be basically working, but there seems to be a frequency limitation. The ADA4841 is copied directly from Analog Devices' website.
Where would I start looking to diagnose this issue?
Thanks,
Aaron
