In Reply to: Slew Rate??? posted by Don on October 8, 1999 at 17:00:18:
Slew rate is the maximum rate at which the output of the amplifier can move. It's generally measured in V/usec. Fortunately, it need only be adequate for the purpose. There's no advantage in simply increasing the number without limit. Slew rate is related to peak voltage and frequency by the equation:Slew rate = 2*pi*f*Vp where Vp is the peak output voltage of the amplifier and f is the frequency of interest.
For example, to get a 50 volt peak sine wave out of an amplifier at 20kHz requires an amplifier with a slew rate of 6.28 volts/usec. With a slight safety margin there's no reason to go faster.
