[2][3] (Some specifications may mandate 100% of the rated power; sometimes referring to the full-power bandwidth.)
It should not be confused with "half-power" bandwidth, only used in conjunction with filter frequency response curves, where it refers to -3dB points in the frequency response of a band-pass filter.
Data sheets for operational amplifiers often use the term (full-)power bandwidth to indicate the highest frequency at which the achievable peak-to-peak output voltage swing is still equal to the DC output voltage range.
In data sheets for commonly available operational amplifiers, slew rate is usually given in volts per microsecond.
Power bandwidth may be specified as a frequency limit or shown in the form of a graph (e.g. as maximum available voltage swing versus frequency, often with power supply voltage as a parameter).
