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/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
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.

THEORY OF OPERATION
OFFSET NULLING
The input offset voltage of the AD842 is very low for a high
speed op amp, but if additional nulling is required, the circuit
shown in Figure 28 can be used.
SETTLING TIME
Figure 29 and Figure 31 show the settling performance of the
AD842 in the test circuit shown in Figure 30.
Settling time is the interval of time from the application of an
ideal step function input until the closed-loop amplifier output
enters and remains within a specified error band.
This definition encompasses the major components that
comprise settling time. They include the following:
Propagation delay through the amplifier.
Slewing time to approach the final output value.
Time of recovery from the overload associated with
slewing.
Linear settling to within the specified error band.
Expressed in these terms, the measurement of settling time
must be accurate to assure the user that the amplifier is worth
consideration for the application.
Figure 28. Offset Nulling (PDIP)
Figure 29. 0.01% Settling Time
Figure 30 shows how measurement of the AD842 0.01% settling
in 100 ns is 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. Under test, the device drives a 300 Ω load.
The input to the error amp is clamped 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 31 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.

AD842 Data Sheet
GROUNDING AND BYPASSING
In designing practical circuits with the AD842, the user must
take some special precautions whenever high frequencies are
involved.
Figure 31. AD842 Settling Demonstrating No Settling Tails
Circuits must be built with short interconnect leads. Use large
ground planes whenever possible to provide a low resistance,
low inductance circuit path; this also minimizes the effects of
high frequency coupling. Avoid sockets because the increased
interlead capacitance can degrade bandwidth.
Use feedback resistors of low enough value to ensure that the
time constant formed with the circuit capacitances does 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, can be used to compensate for these
stray capacitances and to optimize the dynamic performance of
the amplifier in the particular application.
Bypass power supply leads 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.
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 decrease
the dynamic performance of the device, although instability
does not occur unless the load exceeds 100 pF.
USING A HEAT SINK
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
creates a noticeable temperature rise. Use of a small heat sink
improves performance.
TERMINATED LINE DRIVER
The AD842 is optimized for high speed line driver applications.
Figure 32 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, minimizes reflections from the far
end of the cable when equal to the characteristic impedance of
the cable. A back-termination resistor (RBT, also equal to the
characteristic impedance of the cable) can be placed between
the AD842 output and the cable to damp any stray signals
caused by a mismatch between RT and the characteristic
impedance of the cable. This configuration results in a cleaner
signal. With this circuit, the voltage on the line equals VIN
because one half of VOUT is dropped across RBT.
The AD842 has a 100 mA minimum output current and,
therefore, can drive ±5 V into a 50 Ω cable.
Choose the feedback resistors, R1 and R2, carefully. Large value
resistors are desirable to limit the amount of current drawn
from the amplifier output. Large resistors can cause amplifier
instability because the parallel resistance of R1||R2 combines
with the input capacitance (typically 2 pF to 5 pF) to create an
additional pole. The voltage noise of the AD842 is equivalent to
a 5 kΩ resistor; these 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.

OVERDRIVE RECOVERY
Figure 33 shows the overdrive recovery capability of the AD842.
Typical recovery time is 80 ns from negative overdrive and
400 ns from positive overdrive.
