Wideband, High Output Current,
Fast Settling Op Amp
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/
s 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
AD842 is also appropriate for other applications such as high
speed DAC and ADC buffer amplifiers and other wide band-
width circuitry.
APPLICATION HIGHLIGHTS
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.
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.
5. The AD842 is an enhanced replacement for the HA2542.
