*ISL28134 Macromodel
*
*Revision History:
* Revision A, LaFontaine June 17th 2011
* Model for Noise, quiescent supply currents,
*CMRR135dB f = 200Hz, AVOL 174dB f =
*6.5mHz, SR = 1.5V/us, GBWP 3.5MHz.
*Copyright 2011 by Intersil Corporation
*Refer to data sheet “LICENSE STATEMENT”
*Use of this model indicates your acceptance
*with the terms and provisions in the License
*Statement.
*
*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,
*Output current limiting (65mA)
*
*Device performance features NOT
*supported by this model:
*Harmonic distortion effects,
*Disable operation (if any),
*Thermal effects and/or over temperature
*parameter variation,
*Performance variation vs. supply voltage,
*Part to part performance variation due to
*normal process parameter spread,
*Any performance difference arising from
*different packaging,
*Load current reflected into the power supply
*current.
