APPLICATIONS
All current feedback amplifier operational amplifiers are
affected by stray capacitance at the inverting input pin. As a
practical consideration, the higher the stray capacitance on
the inverting input to ground, the higher R
minimize peaking and ringing.
CIRCUIT CONFIGURATIONS
Figure 50 and Figure 51 show typical schematics for non-
inverting and inverting configurations. For current feedback
amplifiers, the value of feedback resistance determines the
stability and bandwidth of the amplifier. The optimum
performance values are shown in Table 5 and should not be
deviated from by more than ±10% to ensure stable operation.
Figure 8 shows the influence varying R
noninverting unity-gain configurations, it is recommended that

VIDEO LINE DRIVER
The AD8000 is designed to offer outstanding performance as a
video line driver. The important specifications of differential
gain (0.02%), differential phase (0.01°), and 650 MHz band-
width at 2 V p-p meet the most exacting video demands. Figure 52
shows a typical noninverting video driver with a gain of +2.
