Where can I find more PSpice models for Op-Amps?

Click For Summary

Discussion Overview

The discussion revolves around the availability of PSpice models for operational amplifiers (Op-Amps), focusing on the limitations of standard libraries and seeking alternative sources for additional models. Participants share their experiences with different SPICE simulation software and where to find models.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses dissatisfaction with the limited number of Op-Amp models available in the PSpice student version libraries.
  • Another participant mentions using LTSpice IV, noting its limitations and suggesting that Analog Devices may offer a free version.
  • A different participant asserts that LTSpice IV's performance is inferior to that of PSpice.
  • One participant recommends downloading SPICE models directly from semiconductor manufacturers' websites, citing Analog Devices and Texas Instruments as sources.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best software or sources for Op-Amp models, with differing opinions on the performance of PSpice compared to LTSpice IV and the availability of models.

Contextual Notes

Limitations include the specific focus on Op-Amp models and the varying performance perceptions of different SPICE software packages.

Hello. I use P-Spice student version and I regret that standard librairies offer very few number of models, especially for Op-Amp's. Is there sites where I can download more components models.
 
Engineering news on Phys.org
I use LTSpice IV. It is free, but it is limited to the linear circuits found at www.linear.com. Analog Devices may have their own free version.
 
I know pretty well this package but its performances are far below those of PSpice.
 
I usually download the SPICE models I need from the semiconductor manufacturers. They provide these models on their websites. Look at Analog Devices, Texas Instruments, etc.
