Does anyone know of a modern op-amp (available) with a frequency compensation input as the very old 709 had?
Op Amp with frequency compensation input
Click For Summary
SUMMARY
The discussion centers on the search for modern operational amplifiers (op-amps) that feature a frequency compensation input, similar to the classic uA709. The user currently possesses two uA709 op-amps and is exploring alternatives for a feedback loop circuit. The ability to tailor the response of these op-amps is emphasized, particularly for experimental purposes such as inserting a right half plane zero in the overall loop. No specific modern replacements have been identified in the discussion.
PREREQUISITES- Understanding of operational amplifier (op-amp) functionality
- Familiarity with frequency compensation techniques
- Knowledge of feedback loop circuit design
- Basic principles of control systems and stability analysis
- Research modern op-amps with frequency compensation features, such as the Texas Instruments OPA series
- Explore the concept of right half plane zeros in control systems
- Study the application of frequency compensation in op-amp circuits
- Investigate alternative op-amps for feedback loop applications, such as the LM318
Electronics engineers, hobbyists working on analog circuit design, and anyone interested in modern alternatives to classic op-amps for feedback loop applications.
