GENERAL DESCRIPTIONThe AD9631 and AD9632 are very high speed and wide
bandwidth 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. Using a voltage feedback architecture, the AD9631/
AD9632’s exceptional settling time, bandwidth, and low
distortion meet the requirements of many applications that
previously depended on current feedback amplifiers. Its
classical op amp structure works much more predictably in
many designs.
8-Lead Plastic Mini-DIP (N), CERDIP (Q),
and SOIC (R) PackagesA proprietary design architecture has produced an amplifier that
combines many of the best characteristics of both current feedback
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 sig-
nal bandwidths.
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, and military versions are packaged in CERDIP.

NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

MAXIMUM POWER DISSIPATIONThe maximum power that can be safely dissipated by these
devices is limited by the associated rise in junction temperature.
The maximum safe junction temperature for plastic encapsu-
lated devices is determined by the glass transition temperature
of the plastic, approximately 150�C. Exceeding this limit tem-
porarily may cause a shift in parametric performance due to a
change in the stresses exerted on the die by the package.
Exceeding a junction temperature of 175�C for an extended
period can result in device failure.
While the AD9631 and AD9632 are internally short circuit
protected, this may not be sufficient to guarantee that the
maximum junction temperature (150�C) is not exceeded under
all conditions. To ensure proper operation, it is necessary to
observe the maximum power derating curves.
