* ADA4530 Macro-model
|
|
* Function: Operational Amplifier

|
|
* Revision History:
|
|
* Rev 0 Oct 2015: ZF/VW
|
|
* Tested by PN at Vsy=+/-5V

* Refer to http://www.analog.com/Analog_Root/static/techSupport/designTools/spicemodels/license
|
|
* for License Statement. Use of this model indicates your acceptance
|
|
* of the terms and provisions in the License Staement.
|
|
*
|
|
* Guard output pins GRD1, GRD2 should be left unconnected for simulation purpose.
|
|
* DNC pin should be left unconnected for simulation purpose.
|
|
* Tested on MultSIm, SiMetrix(NGSpice), PSpice.
|
|
*
|
|
* Not modeled: Distortion, PSRR, Overload Recovery,
|
|
* Shutdown Turn On/Turn Off time.
|
|
*
|
|
* Parameters (typical values) modeled include:
|
|
* Vos, Ibias, Input CM limits and Typ output voltge swing,
|
|
* Open Loop Gain & Phase, Slew Rate, Output current limits, Voltage & Current Noise,
|
|
* Capacitive load drive, supply currents, supply functionality.
|
|
*
|
|
* Not simulated/implemented - performance over temp
|
|
* Parameter variations with supply are not modeled
|
|
*
|
|
* CAUTION!!
|
|
* To aid in convergence, most Spice simulators add a
|
|
* conductance on every node to insure that no node is floating.
|
|
* This is GMIN, and the default value is usually 1E-12. To properly
|
|
* simulate the low input bias current and low current noise, the
|
|
* Spice simulator options have to be set to the following:
|
|
* GMIN=1E-16
|
|
* ABSTOL=1E-16
|
|
* RSHUNT=1E16 (Multisim)
|
|
*
|
|
* When using model in Multisim, comment out the first .ends ADA4530 statement
|
|
* and uncomment the second .ends ADA4530 statement.
|
|
*
|
|
* In some simulations, number of iterations (ITL1) may have to be increased to aid convergence.
