AD841KN

宽带，单位增益稳定，快速建立运算放大器 Wideband, Unity-Gain Stable, Fast Settling Op Amp

**PRODUCT DESCRIPTION**

The AD841 is a member of the Analog Devices family of wide bandwidth operational amplifiers. This high speed/high precision family includes, among others, the AD840, which is stable at a gain of 10 or greater, and the AD842, which is stable at a gain of two or greater and has 100 mA minimum output current drive. These devices are fabricated using Analog Devices’ junction iso lated complementary bipolar CB process. This process permits a combination of dc precision and wideband ac performance previously unobtainable in a monolithic op amp. In addition to its 40 MHz unity-gain bandwidth product, the AD841 offers ex tremely fast settling characteristics, typically settling to within 0.01% of final value in 110 ns for a 10 volt step.
