- * Library of Op Amp subcircuit definitions
- *
- * This is a reduced version of MicroSim's opamp subcircuit library.
- * You are welcome to make as many copies of it as you find convenient.
- *
- * Release date: 86/01/04
- *
- * The parameters in this opamp library were derived from the data
- * sheets for each part. The macromodel used is described in:
- *
- * Macromodeling of Integrated Circuit Operational Amplifiers
- * by Graeme Boyle, Barry Cohn, Donald Pederson, and
- * James Solomon
- * IEEE Journal of Solid-State Circuits, Vol. SC-9, no. 6, Dec. 1974
- *
- * The opamps are modelled at room temperature. The macro model
- * does not track changes with temperature. This library file contains
- * models for nominal, not worst case, devices.
- *
- * Note: Each macromodel consists of a subcircuit definition AND a set
- * of .MODEL statements. The .MODEL statements should be put into
- * the main circuit file along with the subcircuit definition.
