Operational Amplifier key parameters

Click For Summary
SUMMARY

The two key parameters used to describe a non-ideal operational amplifier (Op-Amp) are input offset voltage and input bias current. In the ideal limit, the input offset voltage approaches zero volts, and the input bias current approaches zero amperes. While these two parameters are critical, many other specifications exist that can influence Op-Amp performance depending on the application.

PREREQUISITES
  • Understanding of operational amplifier fundamentals
  • Familiarity with electronic circuit analysis
  • Knowledge of key Op-Amp specifications
  • Basic grasp of ideal vs. non-ideal components
NEXT STEPS
  • Research the impact of input offset voltage on Op-Amp performance
  • Explore the significance of input bias current in circuit design
  • Learn about additional Op-Amp specifications such as slew rate and gain bandwidth product
  • Investigate applications of Op-Amps in real-world circuits
USEFUL FOR

Electronics students, circuit designers, and engineers interested in understanding the performance characteristics of operational amplifiers.

Homework Statement
I'm wondering what are the two key parameters used to describe a non-ideal Op-Amp? And what are the limiting values of these two parameters in the ideal limit?

I can think at least a handful of parameters. Why stop at 2?

Per the forum guidelines (https://www.physicsforums.com/threads/homework-help-guidelines-for-students-and-helpers.686781/) you have to show your work before we can give you help.

So what are your thoughts on Op-Amps?

(Also you might want to re-phrase your last question. I don't understand what you're asking there.)
 
Depends on the applicatio. I can think of at least a dozen op amp specs. All are important depending on the application.
