What is the relation between slew rate and gain-bandwidth product?

When feedback is provided, as in an inverting amplifier, the gain is given by G = – Rf / R1; however, it must be recognized that the magnitude of this gain can never exceed the gain as given by the gain-bandwidth product. slew rate defines the maximum rate at which the output voltage can change with time.

What do you mean by slew rate?

Slew rate is defined as the maximum rate of change of an op amps output voltage, and is given in units of volts per microsecond. Slew rate is measured by applying a large signal step, such as one volt, to the input of the op amp, and measuring the rate of change from 10\% to 90\% of the output signal’s amplitude.

Is higher slew rate better?

Most amplifiers (even the cheap ones) should have a slew rate above 6.3 V/µs. The seemingly high slew rates of most amplifiers are simply good engineering. Having a slew rate that yields a maximum frequency well above the audible range will pretty much eliminate any potential errors and unwanted distortion whatsoever.

How does slew rate affect bandwidth?

Slew Rate is the maximum rate at which the op amp can respond to a large change in input signal. Bandwidth is the maximum rate at which it can respond to small change in signal. In large signal zone its slew rate, in small signal zone its bandwidth.

What is the slew?

1 : to turn (something, such as a telescope or a ship’s spar) about a fixed point that is usually the axis. 2 : to cause to skid : veer slew a car around a turn. intransitive verb. 1 : to turn, twist, or swing about : pivot. 2 : skid.

How does the slew rate affect power bandwidth?

2: The Effect of Slew Rate on Sinusoidal Signals and Power Bandwidth. Slew rate limiting produces an obvious effect on pulse signals. Slew rate limiting can also affect sinusoidal signals. All that is required for slewing to take place is that the signal change faster than the device’s slew rate.

What is the effect of slew rate?

Slew rate decides the capability of an op-amp to change its output rapidly, hence it decides the highest frequency of the operation of a given op-amp. The Slew rate of the op-amp can limit the performance of a circuit and it can distort the output waveform if its limit is exceeded.
