Refers to the ability of an amplifier's output to accurately reflect the input waveforms' rise time transients. An amplifier is said to have a slew rate of so many volts per microsecond. A slew rate of 20 volts per microsecond (20 V/U sec.) means that the amplifier is capable of swinging 20 volts positive or negative in the period of one microsecond.
the maximum rate which an amplifier's output can change, generally expressed in V/µs.
The measure of how fast a large signal can change. It is dimensionally expressed in terms of volts
