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 RF needs to be to
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.
noninverting unity-gain configurations, it is recommended that
Table 5 provides a quick reference for the circuit values, gain,
and output voltage noise.

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.
