Slew Rate in Audio Amplifiers - What Does it Mean ...

Simply, slew rate tells us how high in frequency an amplifier can play for a given voltage level. 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 = …

The slew rate of an op amp or any amplifier circuit is the rate of change in the output voltage caused by a step change on the input. It is measured as a voltage change in a given time - typically V / µs or V / ms. Effect of op amp slew rate. A typical general purpose device may have a slew rate of 10 V / microsecond.

Slew rate is usually specified in V/μs, perhaps because early general purpose op amps had slew rates in the range of 1V/μs. Very high speed amplifiers are in the 1000V/μs range, but you would rarely see it written as 1kV/μs or 1V/ns. Likewise, a nanopower op amp might be specified as 0.02V/μs but seldom as 20V/ms or 20mV/μs.

A composite amplifier to raise the SR of the 741 op-amp. With reference to Figure 3 (a), we find it instructive that OA1 has to amplify only by 0 dB, whereas the amplification by 10 V/V is done by the CFA. Smaller output voltage swings by OA1 ought to ameliorate the slew-rate (SR) considerably. Figure 3. Plots for the PSpice circuit of Figure 2 ...

So how much slew rate is required of an op amp to reproduce a 10V peak signal at 160KHz? Turns out, its 10V/µS. Pretty slow, right? If we get more reasonable, and calculate a slew rate requirement for 5V peak at 50KHz, we only need a paltry …

I am trying to design an op-amp integrator for a Rogowski Coil based current sensor. The op amp I use is THS4631D from Texas Instruments. It has a slew rate of 1000 V/us according to the datasheet. However when I am using it as an integrator the output voltage slews at a much lesser dv/dt and distorts the current waveform.

I have found that the opa2134 (which is so popular), even though it has a slew rate of 20V/uS, is really not a great op amp. It's muddy sounding with a lot of distortion in the highs. It's also not fast enough to have good separation of instruments and high frequency excitement. A set of dual opa827 op amps (slew of 20V/uS) are much better.

Your peak slew-rate is probably in the mid-range, and probably on the order of mV/us max for a 3.3V single rail amp. The OPAx77 series are dual supply, and were always favoured in professional audio apps for their low noise and low distortion. I like the MCP601/6001 amps, but wouldn't use them for audio due to their relatively high noise.
