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 monolithic 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

AD842 is also appropriate for other applications such as high
speed DAC and ADC buffer amplifiers and other wide bandwidth 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.

This definition encompasses the major components which comprise settling time. They include (1) propagation delay through
the amplifier; (2) slewing time to approach the final output value;
(3) the time of recovery from the overload associated with slewing and (4) linear settling to within the specified error band.

Figure 23. Settling Time Test Circuit
Figure 23 shows how measurement of the AD842’s 0.01% settling in 100 ns was accomplished by amplifying the error signal
from a false summing junction with a very high-speed proprietary hybrid error amplifier specially designed to enable testing
of small settling errors. The device under test was driving a
300 Ω load. The input to the error amp is clamped in order to
avoid possible problems associated with the overdrive recovery
of the oscilloscope input amplifier. The error amp gains the
error from the false summing junction by 15, and it contains a
gain vernier to fine trim the gain.

Figure 24 shows the “long term” stability of the settling characteristics of the AD842 output after a 10 V step. There is no
evidence of settling tails after the initial transient recovery time.
The use of a junction isolated process, together with careful
layout, avoids these problems by minimizing the effects of transistor isolation capacitance discharge and thermally induced
shifts in circuit operating points. These problems do not occur
even under high output current conditions.

GROUNDING AND BYPASSING
USING A HEAT SINK
In designing practical circuits with the AD842, the user must
remember that whenever high frequencies are involved, some
The AD842 draws less quiescent power than most precision
high speed amplifiers and is specified for operation without a
heat sink. However, when driving low impedance loads, the current to the load can be 10 times the quiescent current. This will
create a noticeable temperature rise. Improved performance can
be achieved by using a small heat sink such as the Aavid Engineering #602B.
TERMINATED LINE DRIVER
The AD842 is optimized for high speed line driver applications.
Figure 25 shows the AD842 driving a doubly terminated cable
in a gain-of-2 follower configuration. The AD842 maintains a
typical slew rate of 375 V/µs, which means it can drive a ± 10 V,
6.0 MHz signal or a ± 3 V, 19.9 MHz signal.
The termination resistor, RT, (when equal to the characteristic
impedance of the cable) minimizes reflections from the far end
of the cable. A back-termination resistor (RBT, also equal to the
characteristic impedance of the cable) may be placed between
the AD842 output and the cable in order to damp any stray
signals caused by a mismatch between RT and the cable’s characteristic impedance. This will result in a “cleaner” signal. With
this circuit, the voltage on the line equals VIN because one half
of VOUT is dropped across RBT.
Figure 24. AD842 Settling Demonstrating No Settling
Tails
special precautions are in order. Circuits must be built with
short interconnect leads. Large ground planes should be used
whenever possible to provide a low resistance, low inductance
circuit path, as well as minimizing the effects of high frequency
coupling. Sockets should be avoided because the increased
interlead capacitance can degrade bandwidth.
Feedback resistors should be of low enough value to assure that
the time constant formed with the circuit capacitances will not
limit the amplifier performance. Resistor values of less than
5 kΩ are recommended. If a larger resistor must be used, a small
(<10 pF) feedback capacitor connected in parallel with the feedback resistor, RF, may be used to compensate for these stray
capacitances and optimize the dynamic performance of the
amplifier in the particular application.
Power supply leads should be bypassed to ground as close as
possible to the amplifier pins. A 2.2 µF capacitor in parallel with
a 0.1 µF ceramic disk capacitor is recommended.
The AD842 has ± 100 mA minimum output current and, therefore, can drive ± 5 V into a 50 Ω cable.
The feedback resistors, R1 and R2, must be chosen carefully.
Large value resistors are desirable in order to limit the amount
of current drawn from the amplifier output. But large resistors
can cause amplifier instability because the parallel resistance
R1储R2 combines with the input capacitance (typically 2–5 pF) to
create an additional pole. Also, the voltage noise of the AD842
is equivalent to a 5 kΩ resistor, so large resistors can significantly increase the system noise. Resistor values of 1 kΩ or 2 kΩ
are recommended.
If termination is not used, cables appear as capacitive loads and
can be decoupled from the AD842 by a resistor in series with
the output.
CAPACITIVE LOAD DRIVING ABILITY
Like all wideband amplifiers, the AD842 is sensitive to capacitive loading. The AD842 is designed to drive capacitive loads of
up to 20 pF without degradation of its rated performance. Capacitive loads of greater than 20 pF will decrease the dynamic
performance of the part although instability should not occur
unless the load exceeds 100 pF.
