Slew Rate
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The slew rate is the maximum rate of change of an amplifier's output voltage per unit time, typically expressed in volts per microsecond. It determines the amplifier's ability to reproduce fast signal edges without distortion.
Example in context
“When driving a capacitive load, the op-amp's limited slew rate caused visible rounding of the square wave edges.”
“Kapasitif bir yük sürülürken, op-amp'in sınırlı dönüş hızı kare dalga kenarlarında belirgin yuvarlanmaya neden oldu.”
Where engineers use it
Slew rate is a key parameter in op-amp datasheets and design guides. Engineers must consider it when designing high-speed amplifiers, audio circuits, or any application where large signal swings occur at high frequencies to avoid slew‑induced distortion.
Synonyms: SR
Practice: can you use “Slew Rate” at work?
You are designing an audio preamplifier that must pass a 20 kHz sine wave with 10 V peak-to-peak output. Calculate the minimum required slew rate and verify your op-amp selection.
