*****************************************************************************
* Notes: 
* The model meets the following datasheet specs for 5.5V (+-2.75V) operation
* at a temperature of 27C with a load resistance of 10kohms:
* VOS, IIB, Input common-mode Voltage Range, CMRR, noise, Input Capacitance,
* Open-loop voltage gain, GBW, Slew Rate, Output Voltage Swing, 
* Open-loop Output Resistance, Quiescent Current
* Enable and Disable Time, 
* 
* The model meets the following specs over the published operating temperature 
* range:
* IIB
*
* The model does not meet the following datasheet specs:
* phase margin, AOL at 2k load resistance, power-on time,
* Short circuit output current is about half the published value.
*
* The settling time for the macromodel is less than the published device specs.
