Ultralow Distortion, Wide Bandwidth Voltage Feedback Op Amps
REV. A
Information furnished by Analog Devices is believed to be accurate and
reliable. However, no responsibility is assumed by Analog Devices for its
use, nor for any infringements of patents or other rights of third partiesUltralow Distortion, Wide
Bandwidth Voltage Feedback Op Amps
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.

NOTESStresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only, and 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.Specification is for device in free air:
8-Pin Plastic Package: θJA = 90°C/Watt
8-Pin SOIC Package: θJA = 140°C/Watt
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by these de-
vices 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. Exceed-
ing a junction temperature of +175°C for an extended period can
result in device failure.
While the AD9631 and AD9632 are internally short circuit pro-
tected, this may not be sufficient to guarantee that the maxi-
mum junction temperature (+150°C) is not exceeded under all
conditions. To ensure proper operation, it is necessary to ob-
serve the maximum power derating curves.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although these devices feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
