AD9632: 运算放大器
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 two or greater. Utilizing a voltage feedback architecture, the AD9631/AD9632's exceptional 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 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 is offered in industrial (-40°C to +85°C) and military (-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.
