I using an LT1001 precision amplifier and am trying to plot the open-loop frequency response. As I understand it an op-amp can be modelled as a single poled system:
Which from the LT1001 datasheet has the values: DC open-loop gain = 800,000 Gain-Bandwidth Product = 800,000 Dominant-pole frequency = 1Hz
My query is, is my deduction of the dominant pole frequency at 1Hz correct? Does this mean in the frequency response it will almost immediately start to decrease by 20dB/decade?
