* This macromodel has been optimized to model the AC, DC, noise,
* and transient response performance within the device data sheet
* specified limits. Correct operation of this macromodel has been
* verified with DesignSoft TINA Version 9.380.273 SF. For assistance
* with other analog simulation software, please consult the software
* supplier.
