*of this model indicates your acceptance with
*the terms and provisions in the License
*Statement.
*Intended use:
*This Pspice Macromodel is intended to give
*typical DC and AC performance
*characteristics under a wide range of
*external circuit configurations using
*compatible simulation platforms - such as
*iSim PE.
**
*Device performance features supported by
*this model
*Typical, room temp., nominal power supply
*voltages used to produce the following
*characteristics:
*Open and closed loop I/O impedances
*Open loop gain and phase
*Closed loop bandwidth and frequency
*response
*Loading effects on closed loop frequency
*response
*Input noise terms including 1/f effects
*Slew rate
*Input and Output Headroom limits to I/O
*voltage swing
*Supply current at nominal specified supply
*voltages
**
*Device performance features NOT
*supported by this model:
*Harmonic distortion effects
*Disable operation (if any)
*Thermal effects and/or over temperature
*parameter variation
*Limited performance variation vs. supply
*voltage is modeled
*Part to part performance variation due to
*normal process parameter spread
*Any performance difference arising from
*different packaging
