超低失真,宽带电压反馈运算放大器 Ultralow Distortion, Wide Bandwidth Voltage Feedback Op Amps
GENERAL 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 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.
