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.
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/s 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
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.
4. Full differential inputs provide outstanding performance in
all standard high frequency op amp applications where the
circuit gain is 2 or greater.
