The Slew Rate Calculator is a powerful tool used in electronics to measure how quickly the output voltage of a circuit changes concerning time. It is an essential parameter, especially in applications where the speed of voltage changes matters, such as audio amplifiers and communication systems.
Formula of Slew Rate Calculator
The formula for calculating Slew Rate (SR) is as follows:
Slew Rate (SR) = ΔVout / Δt
Where:
- SR is the slew rate, measured in units of volts per second (V/s) or volts per microsecond (V/μs).
- ΔVout is the change in output voltage, measured in volts (V).
- Δt is the change in time, measured in seconds (s) or microseconds (μs).

Example of Slew Rate Calculator
Let’s consider an example to illustrate the practical application of the Slew Rate Calculator. Suppose we have a circuit where the output voltage changes from 2V to 6V in 4 microseconds. Using the formula:
SR = (6V - 2V) / 4μs SR = 1V/μs
The calculated Slew Rate in this example is 1V/μs.
