Real op‑amps have a finite ________ that limits the maximum rate of change of the output voltage.
- A.slew rate
- B.bandwidth
- C.input impedance
- D.output resistance
Model answer
What a good answer should say
- slew rate
Explanation
Why this works
Rule: Slew rate (SR) is the maximum rate of change of the output voltage. Substitution: dV/dt_max = SR.
Working: If SR = 0.5 V/µs, the output can change at 0.5 V per microsecond. Answer: Slew rate.
Units: V/µs. Conclusion: Real op‑amps cannot change output faster than their slew rate.
