slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.

What is slew rate in operational amplifier?
the slew rate of an op-amp represents the maximum rate at which the output can change , no matter how large an input signal is applied the slew rate of an op-amp is specified in V/s or V/mew second.
What are the causes of slew rate?
slew rate is caused by current limiting and the saturation of internal stages of an op-amp when a high-frequency,large amplitude signal is applied.
Why IC741 is not used for high frequency applications?
IC741 has a low slew rate because of the predominance of capacitance present in the circuit at higher frequencies. As frequency increases the output gets distorted due to limited slew rate.
Which is more reasonable using a sine wave or square wave signal to determine slew rate?
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
Calculate full power bandwidth for amplifier using ic741 OP AMP if Voutput is 5 volts peak to peak help?
Slew rate is found by SR = 2*pi*f*V, which f = frequency of signal, V = peak voltage of signal. After you find the slew rate Bom(full power bandwith) = SR / 2piV(pp). So in your case Bom = SR / 2*pi*5Vpp and it is always expressed in units of Hz.
What ia the applicatoin of slew rate?
A: The application is for DAC ADC converters where the fastest slew rate is desirable for fast conversion
How do you calculate slew rate of 741?
One of the practical op-amp limitations is the rate at which the output voltage can change. The limiting rate of change for a device is called its "slew rate". The slew rate for the 741 is 0.5V/microsecond compared to 100V/microsecond for a high-speed op-amp. The LH0063C has a slew rate of 6000V/microsecond. The slew-rate imposes high-frequency limitations on the device. At some critical frequency, an output swing equal to the supply voltages will require a slew rate faster than the maximum slew rate of the device. Above that frequency, the amplitude of distortion-free output voltage swing will be limited. The slew rate is inherently limited by the small internal drive currents of an op-amp but is also limited by internal capacitance designed to compensateagainst high frequency oscillations. Some op-amps are externally compensated and therefore offer some control over the slew rate. The slew rate for a given amplitude V and frequency f is

What is the slew rate of 741ic?
0.5V/us

How is slew rate affect on amplifier?
as it is rate of change of output voltage..so it affect amplifier output

Is the slew rate of the non-inverting amplifier the same as the voltage follower?
It can be but it might not be, it depends on circuit design.
What is a slew shark?
A slew shark is a pike. They are called a slew shark cause they are in every slew you fish in.
