Given that the slew rate of an op-amp is 20v/us. If the expected amplifier output voltage is 10Vp, Determine the maximum operating frequency of the amplifier.
The maximum operating frequency can be calculated using the formula:
f = SR / (2 * Vp)
where SR is the slew rate in V/us and Vp is the peak voltage of the amplifier output.
Substituting the given values, we get:
f = 20 / (2 * 10) = 1 MHz
Therefore, the maximum operating frequency of the amplifier is 1 MHz.
To determine the maximum operating frequency of the amplifier, we need to consider the slew rate and the amplitude of the output voltage.
The formula for calculating the maximum operating frequency (fmax) is:
fmax = SR / (2 * π * Vp)
Where:
SR is the slew rate of the op-amp (20 V/μs in this case)
Vp is the peak-to-peak output voltage (10 Vp in this case)
Let's substitute the given values into the formula:
fmax = 20 / (2 * π * 10)
Simplifying further:
fmax = 1 / (2 * π)
Using a calculator:
fmax ≈ 0.159 Hz
Therefore, the maximum operating frequency of the amplifier is approximately 0.159 Hz.
