* This example schematic is supplied for informational/educational purposes only.
* This demonstrates the use of the symbol UniversalOpamp2(improved version to the UniversalOpamp). You set the SpiceModel to be\nhigher to simulate more aspects of opamp behavior. Level1 is merely a transconductance working into an R||C and doesn't use power\nfrom the supplies. Level2 adds slewrate, current and voltage limits. Level3a adds a second pole. Level3b adds a delay to the dominate\npole response. Noise is modeled at all levels.
