Witryna10 paź 2012 · The extremely IMPORTANT significance to remember, is that CMRR tells how well a differential input amplifier rejects noise that is common to both input lines. Imagine that you have 60Hz noise on both lines. With a good CMRR, very little of that unwanted noise gets passed to the output. It is also a major reason why you see that … WitrynaSlew Rate Calculation. Find out the slew rate if an op-amp is necessary to amplify a signal through 4 volts of peak voltage at a 30kHz of frequency. Vm = 4V and fm = 30kHz. Slew rate (S) = 2πfmVm. Substitute the given values in the above equation. S = 2×3.4x4x30x10^3. = 188.4×10^3 = 188400 V/S or 0.1884V/ μs.
