PRODUCTION DATA
The full-power bandwidth of an amplifier describes the frequency at which the largest sinusoidal signal the amplifier can provide at the output before slew rate induced distortion becomes a dominant source of error. Figure 7-11 illustrates this concept.
If the inputs of the amplifier are driven too far apart (such as when a multiplexer connected to the inverting input changes channels(, a slew boost circuit is enabled to help settling time, but can distort the signal. If low distortion is needed, avoid driving the inputs too far apart from each other. The OPAx828 have a full power bandwidth of 1.2 MHz with 10-VPEAK output voltage. Figure 7-12 illustrates the maximum output voltage as a function of frequency.
