* Refer to "README.DOC" file for License Statement.
* Use of this model indicates your acceptance with
* the terms and provisions in the License Statement.
*
* The following parameters are accurately modeled;
*
*       Open loop gain and phase vs. frequency
*       Output impedance vs. frequency
*       Output clamping voltage and current
*       FET Input common mode range
*       Slew rate
*       Output currents are reflected to V supplies
*       Vos is static and will not vary
*       Distortion is not characterized       
*
