APPLICATIONS INFORMATION
The AD9631/AD9632 are voltage feedback amplifiers well
suited for applications such as photodetectors, active filters,
and log amplifiers. The wide bandwidth (320 MHz), phase
margin (65°), low current noise (2.0 pA/√Hz), and slew rate
(1300 V/s) of the devices give higher performance capabilities
to these applications over previous voltage feedback designs.
With a settling time of 16 ns to 0.01% and 11 ns to 0.1%, the
devices are an excellent choice for DAC I/V conversion. The
same characteristics along with low harmonic distortion make
them a good choice for ADC buffering/amplification. With
superb linearity at relatively high signal frequencies, the
OPERATION AS A VIDEO LINE DRIVER
The AD9631/AD9632 have been designed to offer outstanding
performance as video line drivers. The important specifications
of differential gain (0.02%) and differential phase (0.02°) meet
the most exacting HDTV demands for driving video loads.

ACTIVE FILTERS
The wide bandwidth and low distortion of the AD9631/
AD9632 are ideal for the realization of higher bandwidth active
filters. These characteristics, while being more common in
many current feedback op amps, are offered in the AD9631/
AD9632 in a voltage feedback configuration. Many active
filter configurations are not realizable with current feedback
amplifiers.
A multiple feedback active filter requires a voltage feedback
amplifier and is more demanding of op amp performance than
other active filter configurations, such as the Sallen-Key. In
general, the amplifier should have a bandwidth that is at least
10 times the bandwidth of the filter if problems due to phase
shift of the amplifier are to be avoided.
Figure 65 is an example of a 20 MHz low-pass multiple feedback
active filter using an AD9632.
