PRODUCT DESCRIPTION

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.

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).

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
