The slew rate of an operational amplifier is the maximum rate at which the output voltage can change with respect to time. It is typically expressed in volts per microsecond (V/μs).
Slew rate is calculated using the formula:
Slew Rate = ΔVo / Δt
Where:
- ΔVo is the change in output voltage
- Δt is the time taken for this change
From the output waveform shown in this question, we need to determine which option correctly represents the slew rate. By analyzing the voltage swing and the time period from the waveform, the slew rate can be calculated.
The correct answer is (c) 20.66V/μs, as it represents the maximum rate at which the op-amp output can change based on the given waveform parameters.
Understanding slew rate is crucial in practical op-amp circuit design, as it limits the maximum frequency and amplitude of signals that can be processed without distortion.
