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.

APPLICATION HIGHLIGHTS

1. The high slew rate and fast settling time of the AD840 make

it ideal for DAC and ADC buffers, line drivers and all types

of video instrumentation circuitry.

PRODUCT DESCRIPTION

The AD840 is a member of the Analog Devices’ family of wide

bandwidth operational amplifiers. This high speed/high precision

family includes, among others, the AD841, which is unity-

gain 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.

2. The AD840 is truly a precision amplifier. It offers 12-bit

accuracy to 0.01% or better and wide bandwidth, perfor-

mance previously available only in hybrids.

3. The AD840’s thermally balanced layout and the high speed

of the CB process allow the AD840 to settle to 0.01% in

100 ns without the long “tails” that occur with other fast op

amps.

4. Laser wafer trimming reduces the input offset voltage to

0.3 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.

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).

5. Full differential inputs provide outstanding performance

in all standard high frequency op amp applications where

circuit gain will be 10 or greater.

6. The AD840 is an enhanced replacement for the HA2540.

The 400 V/µs slew rate of the AD840, along with its 400 MHz

gain bandwidth, ensures excellent performance in video and

pulse amplifier applications. This amplifier is ideally suited for

use in high frequency signal conditioning circuits and wide
