* BEGIN MODEL NCS2008
*
* MODEL FEATURES INCLUDE OUTPUT SWING, OUTPUT CURRENT
* THROUGH THE SUPPLY RAILS, RAIL-TO-RAIL OUTPUT STAGE,
* CMR AND VOS SENSITIVE TO DIFFERENT REGIONS OF INPUT
* COMMON MODE VOLTAGE, OUTPUT CURRENT LIMIT, ASYMETRICAL
* SLEW RATE WITH TEMPERATURE EFFECTS, OUTPUT SWING
* VERSUS CURRENT, OPEN LOOP GAIN AND PHASE WITH RL
* AND CL EFFECTS, POWER SUPPLY REJECTION WITH FREQUENCY
* EFFECTS, INPUT VOLTAGE NOISE WITH 1/F, INPUT CURRENT
* NOISE, INPUT BIAS CURRENT WITH TEMPERATURE EFFECTS,
* INPUT CM AND DIFF CAPACITANCE, INPUT COMMON MODE RANGE,
* OFFSET TEMPERATURE EFFECTS, INPUT AND OUTPUT CLAMPS
* TO THE RAILS, AND QUIESCENT CURRENT.
* MODEL TOTAL SUPPLY VOLTAGE RANGE IS 1.8 TO 5.5 V.
* MODEL TEMP RANGE IS -40 TO +125 DEG C.
* NOTE THAT MODEL IS FUNCTIONAL OVER THIS RANGE BUT
* NOT ALL PARAMETERS TRACK THOSE OF THE REAL PART.
*
* NOTE - FOR ACCURATE BIAS CURRENTS AT ROOM AND COLD
* SET THE SPICE ANALYSIS OPTIONS AS FOLLOWS :
* RELTOL 0.001 TO 0.00001 AND GMIN 1E-12 TO 1E-14.
* SET BOTH OF THESE OPTIONS AS SMALL AS WILL ALLOW
* CONVERGANCE ON YOUR SIMULATOR. IF YOU ARE USING
* LTSPICE17 ADD THE OPTIONS PLOTRELTOL=1E-4 AND
* PLOTVNTOL=1E-6 FOR MORE ACCURATE OUTPUT WAVEFORM
* PLOTTING.
*
* IF YOU ARE USING LTSPICE17 ADD THE OPTIONS
* PLOTRELTOL=1E-4 AND PLOTVNTOL=1E-6 FOR MORE
* ACCURATE TIME DOMAIN WAVEFORM PLOTTING.
