Ever wondered why your op-amp doesn’t behave exactly as the textbook says? 🤔
In this video, we break down two critical concepts in op-amp design: common-mode voltage and the common-mode rejection ratio (CMRR).
✅ You’ll learn:
What common-mode voltage really means (in plain English)
Why real op-amps don’t perfectly reject it
How datasheet specs like CMRR are measured and interpreted
A practical look at the LM741 and why its limits matter
How instrumentation amplifiers solve common-mode problems
By the end, you’ll clearly see why CMRR is one of the most important specs when working with difference amplifiers and sensor circuits.
