Hi. I'm newbie in circuit simulation.
I designed amplifier using ad8000. I simulated using ad8000 spice model provided from analog device.
this is my circuit
I followed document TI application report SLOA070
these are steps what I did.
step 1 : open pspice model editor - file - new
step 2 : model - import and then File - save.
step 3 : File - export to capture part library and then I saw STATUS success notification.
step 4 : I open Orcad Capture program, then File - Open - Library, Browse AD8000 library.
step 5 : I saved it. and I made circuit as the picture to simulate.(of course I made new simulation profile)
step 6 : edit simulation profile - configuration file - library - browse AD8000 library file - add as global.
step 7 : I did transient simulation.
This is the result what I got from session log.
Is there anyone same result like me?
What do you think of my problem??
Thanks in advance.
May I know what your intended application is?
Anyway, I replicated your circuit and run it successfully.
Do these instead.
Step 1: Make folder for design files (i.e AD8000 application)
Step 2: Open AD8000.cir file; File >> Save as>> AD8000.lib (the same folder, this will be your library file)
Step 3: Open Model Editor
Step 4: File>>Expert to Capture Part Library (If you open your folder you should find AD8000.olb file)
Step 5: Open Orcad Capture (Allegro Design Entry CIS) >> New Project >> Analog or Mixed A/D >>Create Blank Project
Step 6: Place Part (P) >> Add Library>>AD8000.olb
Step 7: Create schematic>>New Simulation Profile>>Configuration Files>> Library>> Browse>> AD8000.lib>>Add to Design or Add as Global >> OK
Step 8: Run
This should work.
