The formula to calculate the Slew Rate (SR) is:
\[ SR = \frac{Vout(90\%) - Vout(10\%)}{t(90\%) - t(10\%)} \]
Where:
A slew rate is defined as the maximum rate of change of an op amp's output voltage from a signal step of 90%-10%. It is a critical parameter in electronics that affects the performance of amplifiers and other circuits.
Let's say the voltage output at 90% (Vout(90%)) is 5 V, the voltage output at 10% (Vout(10%)) is 1 V, the time at 90% (t(90%)) is 0.002 s, and the time at 10% (t(10%)) is 0.001 s. Using the formula:
\[ SR = \frac{5 - 1}{0.002 - 0.001} = 4000 \, \text{V/s} \]
So, the slew rate (SR) is 4000 V/s.
