The AD9631 and AD9632 are very high speed and wide bandwidthamplifiers. They are an improved performance alternaTIveto the AD9621 and AD9622. The AD9631 is unity gain stable.The AD9632 is stable at gains of 2 or greater. Using a voltagefeedback architecture, the AD9631/AD9632’s excepTIonal settlingTIme, bandwidth, and low distorTIon meet the requirements ofmany applications that previously depended on current feedbackamplifiers. Its classical op amp structure works much morepredictably in many designs.A proprietary design architecture has produced an amplifierthat combines many of the best characteristics of both currentfeedback and voltage feedback amplifiers. The AD9631 andAD9632 exhibit exceptionally fast and accurate pulse response(16 ns to 0.01%) as well as extremely wide small signal and largesignal bandwidth and ultralow distortion. The AD9631 achieves–72 dBc at 20 MHz, and 320 MHz small signal and 175 MHzlarge signal bandwidths.These characteristics position the AD9631/AD9632 ideally fordriving flash as well as high resolution ADCs. Additionally, thebalanced high impedance inputs of the voltage feedback architectureallow 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.
