* This example schematic is supplied for informational/educational purposes only.
* This demonstrates the use of the symbol UniversalOpamp. You set the SpiceModel to be higher to simulate more aspects of opamp behavior.\nLevel1 is merely a transconductance working into an R||C and doesn't use power from the supplies. Level2 adds slewrate, current and\nvoltage limits. Level3a adds a second pole. Level3b adds a delay to the dominate pole response. Noise is modeled at all levels.
