APPLICATIONS INFORMATION
GAIN CONFIGURATIONS
Unlike conventional voltage feedback amplifiers, the feedback
resistor has a direct impact on the closed-loop bandwidth and
stability of the current feedback op amp circuit. Reducing the
resistance below the recommended value can make the amplifier
response peak and can even become unstable. Increasing the
size of the feedback resistor reduces the closed-loop bandwidth.
Table 5 provides a convenient reference for quickly determining
the feedback and gain set resistor values, and the small and
large signal bandwidths for common gain configurations. The
feedback resistors in Table 5 have been optimized for 0.1 dB
flatness frequency response.

RGB VIDEO DRIVER
Figure 40 shows a typical RGB driver application using bipolar
supplies. The gain of the amplifier is set at +2, where RF = RG =
464 . The amplifier inputs are terminated with shunt 75
resistors, and the outputs have series 75 resistors for proper
video matching. In Figure 40, the POWER DOWN pins are not
shown connected to any signal source for simplicity. If the power-
down function is not used, it is recommended that the POWER
DOWN pins be tied to the positive supply and not be left floating
(not connected).
In applications that require a fixed gain of +2, as previously
mentioned, the designer may consider the ADA4862-3.
The ADA4862-3 is another high performance triple current
feedback amplifier. The ADA4862-3 has integrated feedback
and gain set resistors that reduce board area and simplify designs.
