*
*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,
*Output current limiting (current will limit at
*40mA),
*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 source,
*Load current reflected into the power supply
*current.
