I think the key aspects that this question was testing was that you understand that you need to convert the RMS voltage to a peak voltage to calculate the Slew Rate, and that you can do some basic rearrangement of the Slew Rate formula. Also you need to recognise 748.5e+9 equates to ...
Slew rate is one of the most important performance indicators reflecting the dynamic response of an operational amplifier, and the minimum requirement for undistorted sinusoidal signals is shown in the following formula: Different types of resolvers have different requirements for the amplitude and freque...
This next section showing how to calculate slew rate is included only for completeness: If a preamplifier has a slew rate of 1 volt per microsecond, then it can output about 10 volts peak-to-peak at 20 KHz without adding slew rate-induced distortion. The formula to determine the minimum ...
Slew Rate Formula & Its Units The slew rate formula is (S) = ΔVout/Δt. The slew rate units are V/μs or Volts per second. Slew Rate Circuit Diagram The slew rate measurement circuit is shown below. The slew rate of an op-amp can be simply measured by providing a step signal t...
Following the simple formula that relates voltage, current, capacitance, and time for a capacitor: ic= C x dv/dt where ic is the capacitor current, C is Capacitance and dv/dt is the rate of change of voltage. From this, we can get that ...
Sonow that we know what it is, how much slew rate is enough? The basic formula toobtain a minimum necessary slew rate for an amplifier is: SlewRate = 2 xπ x Frequency xPeak Voltage As you’ll note, the factors we need to fill in are howhigh in frequency we want to go and how...
So now that we know what it is, how much slew rate is enough? The basic formula to obtain a minimum necessary slew rate for an amplifier is: Slew Rate = 2 x π x Frequency x Peak Voltage As you’ll note, the factors we need to fill in are how high in frequency we want to go...
We'll start with the slew rate. The slew rate equals, 2πfV. If we want to output a 10V signal with a frequency of 50KHz, we plug these values into the formula, slew rate= 2πfV= 2(3.14)(50,000Hz)(10V) = 3,140,000. This value is the slew rate expressed in volts per se...
output stage, is insufficient, then the slew rate cannot be described by the foregoing formula. Therefore, a second stage amplifier 102 is necessary to improve the driving ability. In this manner, it is necessary to increase the size of the second stage. This then causes an increase of the...
There are two controlling elements in the slew rate formula, I_C1 and C1. It can be seen from the table, in Figure 4, that the design trade-off is between the C1 value and IC_1. By keeping I_C1 low (<10A) one can swing close to the supply rails of U1 and get a ...
