This method is also helpful if you need many opamps in your circuit and you bump into the "maximum devices" limitation of the evaluation version of PSpice. NOTE: The "E" device does not model power supply saturation, so the output voltage can become extremely large if the circuit causes the VCVS input voltage to exceed a few microvolts.
