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.

AD841 makes it the preferred choice for data acquisition

applications which 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.

APPLICATION 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 previ-

ously available only in hybrids.

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.

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.

The 300 V/µs 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

4. Laser wafer trimming reduces the input offset voltage to

1 mV max on the K grade, thus eliminating the need for

external offset nulling in many applications. Offset null

pins are provided for additional versatility.

5. The AD841 is an enhanced replacement for the

HA2541.
