GENERAL DESCRIPTION
The AD841 is a member of the Analog Devices, Inc., family of
wide bandwidth operational amplifiers. This high speed/high
precision family includes 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 perfor-
mance previously unobtainable in a monolithic op amp. In
addition to its 40 MHz unity-gain bandwidth product, the
AD841 offers extremely fast settling characteristics, typically
settling to within 0.01% of final value in 110 ns for a 10 V 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 15 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
bandwidth active filters. The extremely rapid settling time of
the AD841 makes it the preferred choice for data acquisition
applications that require 12-bit accuracy. The AD841 is also
appropriate for other applications such as high speed DAC and
ADC buffer amplifiers and other wide bandwidth circuitry.
PRODUCT HIGHLIGHTS
1. The high slew rate and fast settling time of the AD841
make it ideal for DAC and ADC buffers, and all types of
video instrumentation circuitry.
2. The AD841 is a precision amplifier. It offers accuracy to
0.01% or better and wide bandwidth performance
previously available only in hybrids.
3. The AD841’s thermally balanced layout and the speed of
the CB process allow the AD841 to settle to 0.01% in 110 ns
without the long tails that occur with other fast op amps.
4. Laser wafer trimming reduces the input offset voltage to
1 mV maximum on the K grade, thus eliminating the need
for external offset nulling in many applications. Offset null
pins are provided for additional versatility.
