<Dd> S R = max (d v o u t (t) d t) (\ displaystyle \ mathrm (SR) = \ max \ left (\ left (\ frac (dv_ (\ mathrm (out)) (t)) (dt)) \ right \ right)) </Dd> <P> where v o u t (t) (\ displaystyle v_ (\ mathrm (out)) (t)) is the output produced by the amplifier as a function of time t . </P> <P> The slew rate can be measured using a function generator (usually square wave) and an oscilloscope . The slew rate is the same, regardless of whether feedback is considered . </P> <P> There are slight differences between different amplifier designs in how the slewing phenomenon occurs . However, the general principles are the same as in this illustration . </P>

In order to obtain fast slew rate an operational amplifier must have
