PRODUCT DESCRIPTION

TOP VIEW

The AD842 is a member of the Analog Devices family of wide

bandwidth operational amplifiers. This device is 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 mono-

lithic op amp. In addition to its 80 MHz gain bandwidth, the

AD842 offers extremely fast settling characteristics, typically

settling to within 0.01% of final value in less than 100 ns for a

10 volt step.

AD842 is also appropriate for other applications such as high

speed DAC and ADC buffer amplifiers and other wide band-

width circuitry.

APPLICATION HIGHLIGHTS

The AD842 also offers a low quiescent current of 13 mA, a high

output current drive capability (100 mA minimum), a low input

voltage noise of 9 nV√Hz and a low input offset voltage (1 mV

maximum).

1. The high slew rate and fast settling time of the AD842 make

it ideal for DAC and ADC buffers amplifiers, lines drivers

and all types of video instrumentation circuitry.

2. The AD842 is a precision amplifier. It offers accuracy to

0.01% or better and wide bandwidth; performance previously

available only in hybrids.

The 375 V/µs slew rate of the AD842, along with its 80 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

bandwidth active filters. The extremely rapid settling time of

the AD842 makes this amplifier the preferred choice for data

acquisition applications which require 12-bit accuracy. The

3. Laser-wafer trimming reduces the input offset voltage of

1 mV max, thus eliminating the need for external offset

nulling in many applications.

4. Full differential inputs provide outstanding performance in

all standard high frequency op amp applications where the

circuit gain will be 2 or greater.

*Covered by U.S. Patent Nos. 4,969,823 and 5,141,898.

5. The AD842 is an enhanced replacement for the HA2542.
