I am trying to match an op amp (OP27) to its data sheet while doing some stability analysis tasks in LTSpice. I am following the video provided here (http://www.linear.com/solutions/4449). However, when I follow the details of the video tutorial for the specific op amp I am interested in, I do not find the sorts of results expected based on the datasheet.
For instance, the DC gain is >140 dB and the low-frequency rolloff starts much below 1 Hz, in contrast to the Analog Devices datasheet.
Are op amp models in LTSpice generally not that accurate to real devices?
