AD840的产品描述：
The AD840 is a member of the Analog Devices’ family of wide andwidth operational amplifiers. This high speed/high precision amily includes, among others, the AD841, which is unity- ain stable, 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 isolated 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 400 MHz gain bandwidth product, the AD840 offers extremely fast settling characteristics, typically settling to within 0.01% of final value in 100 ns for a 10 volt step.
The AD840 remains stable over its full operating temperature range at closed-loop gains of 10 or greater. It also offers a low quiescent current of 12 mA maximum, a minimum output current drive capability of 50 mA, a low input voltage noise of 4 nV/√Hz and a low input offset voltage of 0.3 mV maximum (AD840K).
The 400 V/μs slew rate of the AD840, along with its 400 MHz ain bandwidth, ensures excellent performance in video and pulse amplifier applications. This amplifier is ideally suited for use in high frequency signal conditioning circuits and wid bandwidth active filters. The extremely rapid settling time of the
AD840 makes it the preferred choice for data acquisition appli-cations which require 12-bit accuracy. The AD840 is also ap-propriate for other applications such as high speed DAC and ADC buffer amplifiers and other wide bandwidth circuitry.
