I am new to PSpice software. I want to place an operational amplifier (AD8221, OP1177) and a modulator/demodulator(AD630AR) in pspice for my simulation.
I am unable to find these items. If any body knows how I can place these things then please help me.
You can find macromodels for them at Analog Devices page:
- AD8221
http://www.analog.com/Analog_Root/static/techSupport/designTools/spiceModels/license/spice_general.html?cir=ad8221.cir
- OP1177
http://www.analog.com/Analog_Root/static/techSupport/designTools/spiceModels/license/spice_general.html?cir=op1177.cir
- AD630
http://www.analog.com/Analog_Root/static/techSupport/designTools/spiceModels/license/spice_general.html?cir=ad630.cir
Thankyou so much Mr. Kurtaj. One more thing can you tell me how to include these into library because it contains the .cir format which is not the same as others in the exixting library.....

Hello,
As mentioned above, you can get the pure model description from the manufactureres. However, this is not sufficient. These circuit files must be combined with a corresponding symbol library within your program. Otherwise you cannot use it on the screen (a specific triangular symbol must be defined) .
I am sure you will find a relevant procedure (how to include...) in the net via google.
To create graphical symbol for schematics drawing you may find helpful Texas Instruments Application Report

and for textual usage this Tutorial (original Tutorial link is not working)

You can find also many others.
From Spice family LTspice is worth a try.
Hi Muhammad
I think most of your question has been answered, but in the full version of PSpice you should find the AD630 in the ANLG_DEV.OLB library. I just checked and it is there, and the associated model (.lib file) is also present. Maybe you need to add this library? However, if that is not successful and you are using the evaluation version then go to my web site at:
http://www.electronics.dit.ie/staff/ptobin/pspicebooks.htm
you will find a PDF on how to associate the model with the symbol. Scroll down to 'Adding library files' and download the PDF.
The AD633 is also a useful device as a modulator and this is also there as well.
Paul - thank you for directing us to your web site. Good information.
PS: I love Dublin.
Hi Lutz, Muhammad, you are most welcome. If you want the complete simulation files(i.e. the OPJ file) to any of the circuits from my books please email me and I'll send you a zipped file. The .DSN files are available on the website but the .OPJ give the simulation settings etc. and are ready to run.

I landed in Frankfort from Nanjing University last week and would have loved to stop over but my connecting flight to Dublin was in 2 hours! I'd love to give a seminar on PSpice in Germany, so maybe someday......
Just to share with you the additional library Pspice model.. its free download.. http://robustdesignconcepts.com/files/pspice/pmindex.htm
you can find AD8221, OP1177 and AD630 at :" https://www.pspice.com/models/analog-devices "
Hi ! I need to find the following library for the simulation TL074CN and AD633JR. Can you help me, please? Thanks!
