GENERAL DESCRIPTION

The AD842 is a member of the Analog Devices, Inc. family of

wide bandwidth operational amplifiers. This device is fabricated

using the Analog Device junction isolated complementary

bipolar (CB) process. This process permits a combination of dc

precision and wideband ac performance previously unobtain-

able in a monolithic op amp. In addition to its 80 MHz gain

bandwidth product, the AD842 offers extremely fast settling

characteristics, typically settling to within 0.01% of final value

in less than 100 ns for a 10 V step.

acquisition applications requiring 12-bit accuracy. The AD842

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 AD842

make it ideal for DAC and ADC buffers amplifiers, line

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.

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

1.5 mV maximum, thus eliminating the need for external

offset nulling in many applications.

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

(1.5 mV maximum).

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

gain bandwidth product, 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

4. Full differential inputs provide outstanding performance in

all standard high frequency op amp applications where the

circuit gain is 2 or greater.
