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/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, 320 MHz small signal bandwidth, and  
175 MHz large signal bandwidths.

7.0 nV/√Hz spectral noise density  
High speed  
Slew rate: 1300 V/μs  
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.  
Settling time to 0.01%, 2 V step: 16 ns

APPLICATIONS  
The AD9631/AD9632 are offered in the industrial (−40°C to  
+85°C) temperature range. They are available in PDIP and SOIC.

GENERAL DESCRIPTION

The AD9631/AD9632 are very high speed and wide bandwidth  
amplifiers. The AD9631 is unity gain stable. The AD9632 is  
stable at gains of 2 or greater. Using a voltage feedback  
architecture, the exceptional settling time, bandwidth, and low  
distortion of the AD9631/AD9632 meet the requirements of  
many applications that previously depended on current feed-  
back amplifiers. Its classical op amp structure works much more  
predictably in many designs.
