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.
Unlike many high frequency amplifiers, the AD841 requires no
external compensation. It remains stable over its full operating
temperature range. 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 13 nV/ Hz and low input
offset voltage of 1 mV maximum.
The 300 V/ s slew rate of the AD841, along with its 40 MHz
gain bandwidth, ensures excellent performance in video and
pulse amplifier applications. This amplifier is well suited for use
in high frequency signal conditioning circuits and wide band-
width active filters. The extremely rapid settling time of the
