I would like to know what is the difference in the die structures of the following Op Amps

  • AD8620
  • AD8512
  • AD8513
  • OPA4227


The main reason to know more about the die structures is to know how much the IC's will dissipate power supply current/energy. I came across some material which tells that even though the IC's and their working performance are same, the power supply current for each will be dependent on the die structure of the particular IC.
