*ISL28118_218 Macromodel - covers
following *products
*ISL28118
*ISL28218
*
*Revision History:
* Revision A, LaFontaine February 8th 2011
* Model for Noise, supply currents, CMRR
*120dB f = 40kHz, AVOL 136dB f = 0.5Hz
* SR = 1.2V/us, GBWP 4MHz.
*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,
*
*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,
*Load current reflected into the power supply
*current.
