General Description
The MAX4389/MAX4390/MAX4392–MAX4396 family of
op amps are unity-gain stable devices that combine high-
speed performance, rail-to-rail outputs, and disable mode.
These devices are targeted for applications where an
input or an output is exposed to the outside world, such
as video and communications.
The MAX4389/MAX4390/MAX4392–MAX4396 operate
from a single 4.5V to 11V supply or from dual ±2.25V to
±5.5V supplies. The common-mode input voltage range
extends to the negative power-supply rail (ground in
single-supply applications). The MAX4389/MAX4390/
MAX4392–MAX4396 consume only 5.5mA of quiescent
supply current per amplifier while achieving a 85MHz
-3dB bandwidth, 27MHz 0.1dB gain flatness, and a
500V/μs slew rate. Disable mode sets the outputs to high
impedance while consuming only 450μA of current.
The MAX4389 single, MAX4393 dual, MAX4394 triple,
and MAX4396 quad include disable capabilities. The
MAX4389 and MAX4390 are available in ultra-small, 6-pin
SC70 packages.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Pin Description
Detailed Description
The MAX4389/MAX4390/MAX4392–MAX4396 are
dual-supply, rail-to-rail, voltage-feedback amplifiers that
employ current-feedback techniques to achieve 500V/μs
slew rates and 85MHz bandwidths. Excellent harmonic
distortion and differential gain/phase performance make
these amplifiers an ideal choice for a wide variety of video
and RF signal-processing applications.
Applications Information
The output voltage swings to within 200mV of each supply
rail. Local feedback around the output stage ensures low
open-loop output impedance to reduce gain sensitivity to
load variations. The input stage permits common-mode
voltages to the negative supply and to within 2.25V of the
positive supply rail.
Choosing Resistor Values
Unity-Gain Conguration
The MAX4389/MAX4390/MAX4392–MAX4396 are inter-
nally compensated for unity gain. When configured
for unity gain, a 24Ω resistor (RF) in series with the
feedback path optimizes AC performance. This resistor
improves AC response by reducing the Q of the parallel
LC circuit formed by the parasitic feedback capacitance
and inductance.

Pin Description (continued)
Video Line Driver
The MAX4389/MAX4390/MAX4392–MAX4396 are low-
power, voltage-feedback amplifiers featuring large-signal
(2VP-P) bandwidths of 90MHz and 0.1dB large-signal
gain flatness of 24MHz. They are designed to mini-
mize differential-gain error and differential-phase error
to 0.015% and 0.015°, respectively. They have a 21ns
settling time to 0.1%, 500V/μs slew rates, and output-
current-drive capability of up to 50mA making them ideal
for driving video loads.
Inverting and Noninverting Congurations
Select the gain-setting feedback (RF) and input (RG)
resistor values to fit your application. Large resistor val-
ues increase voltage noise and interact with the ampli-
fier’s input and PCB capacitance. This can generate
undesirable poles and zeros and decrease bandwidth or
cause oscillations. For example, a noninverting gain-of-
two configuration (RF = R
G) using 2kΩ resistors, com-
bined with 1pF of amplifier input capacitance and 1pF of
PCB capacitance, causes a pole at 79.6MHz. Since this
pole is within the amplifier bandwidth, it jeopardizes stabil-
ity. Reducing the 2kΩ resistors to 100Ω extends the pole
frequency to 1.59GHz, but could limit output swing by
adding 200Ω in parallel with the amplifier’s load resistor
(Figures 1a and 1b).
Layout and Power-Supply Bypassing
The MAX4389/MAX4390/MAX4392–MAX4396 operate
from single 4.5V to 11V or from dual ±2.25V to ±5.5V sup-
plies. Bypass each supply with a 0.1μF capacitor as close
to the pin as possible.
Maxim recommends using microstrip and stripline tech-
niques to obtain full bandwidth. To ensure that the PCB
does not degrade the amplifier’s performance, design it
for a frequency greater than 1GHz. Pay careful attention
to inputs and outputs to avoid large parasitic capacitance.
Whether or not you use a constant-impedance board,
observe the following design guidelines:
● Do not use wire-wrap boards; they are too inductive.
● Do not use IC sockets; they increase parasitic capaci-
tance and inductance.
● Use surface-mount instead of through-hole compo-
nents for better, high-frequency performance.
● Use a PCB with at least two layers; it should be as free
from voids as possible.
● Keep signal lines as short and as straight as possible.
Do not make 90° turns; round all corners.
Low-Power Disable Mode
The MAX4389/MAX4393/MAX4394/MAX4396 feature a
disable function that allows the amplifiers to be placed
in a low-power, high-output impedance state. When the
disable pin (DISABLE) is active, the amplifier’s output
impedance is 95kΩ. This high resistance and the low
2pF output capacitance make the MAX4389/MAX4390/
MAX4392–MAX4396 in RF/video multiplexer or switch
applications. For larger arrays, pay careful attention to
capacitive loading (see the Output Capacitive Loading
and Stability section).
Output Capacitive Loading and Stability
The MAX4389/MAX4390/MAX4392–MAX4396 are opti-
mized for AC performance. They are not designed to drive
highly reactive loads, which decrease phase margin and
may produce excessive ringing and oscillation. Figure
2 shows a circuit that eliminates this problem. Figure
3 is a graph of the Optimal Isolation Resistor (RS) vs.
Capacitive Load. Figure 4 shows how a capacitive load
causes excessive peaking of the amplifier’s frequency
response if the capacitor is not isolated from the ampli-
fier by a resistor. A small isolation resistor (usually 10Ω to
15Ω) placed before the reactive load prevents ringing and
oscillation. At higher capacitive loads, AC performance is
controlled by the interaction of the load capacitance and
the isolation resistor. Figure 5 shows the effect of a 15Ω
isolation resistor on closed-loop response.
