The 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 2 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.A 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 signal 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 architecture
allow maximum flexibility when designing active filters.
The AD9631/AD9632 are offered in the industrial (–40C to
+85C) temperature range. They are available in PDIP and SOIC.
