Ultralow Distortion, Wide
Bandwidth Voltage Feedback Op Amps
AD9631/AD9632
These characteristics position the AD9631/AD9632 ideally for
driving flash as well as high resolution ADCs. Additionally, the
balanced high impedance inputs of the voltage feedback archi-
tecture allow maximum flexibility when designing active filters.
The AD9631 is offered in industrial (–40

C to +85
°
C) and mili-
tary (–55

C to +125
°
C) temperature ranges and the AD9632 in
industrial. Industrial versions are available in plastic DIP and
SOIC; MIL versions are packaged in cerdip.

PRODUCT DESCRIPTION
The AD9631 and AD9632 are very high speed and wide band-
width amplifiers. They are an improved performance alternative
to the AD9621 and AD9622. The AD9631 is unity gain stable.
The AD9632 is stable at gains of two or greater. Utilizing a
voltage feedback architecture, the AD9631/AD9632’s excep-
tional settling time, bandwidth, and low distortion meet the
requirements of many applications which previously depended
on current feedback amplifiers. Its classical op amp structure
works much more predictably in many designs.
A proprietary design architecture has produced an amplifier that
combines many of the best characteristics of both current feed-
back and voltage feedback amplifiers. The AD9631 and
AD9632 exhibit exceptionally fast and accurate pulse response
(16 ns to 0.01%) as well as extremely wide small signal and
large signal bandwidth and ultralow distortion. The AD9631
achieves –72 dBc at 20 MHz and 320 MHz small signal and
175 MHz large signal bandwidths.
