General Description
The MAX4380–MAX4384 family of op amps are unity-
gain-stable devices that combine high-speed perfor-
mance, Rail-to-Rail®outputs, and high-impedance
disable mode. These devices operate from a +4.5V to
+11V single supply or from ±2.25V to ±5.5V dual sup-
plies. The common-mode input voltage range extends
beyond the negative power-supply rail (ground in sin-
gle-supply applications).
The MAX4380–MAX4384 require only 5.5mA of quies-
cent supply current per op amp while achieving a
210MHz -3dB bandwidth, 55MHz 0.1dB gain flatness
and a 485V/µs slew rate. These devices are an excel-
lent solution in low-power/low-voltage systems that
require wide bandwidth, such as video, communica-
tions, and instrumentation.
The MAX4380 single with disable is available in an ultra-
small 6-pin SC70 package.

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 at 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.

Op Amps with Rail-to-Rail Outputs and Disable
10 ______________________________________________________________________________________10 ______________________________________________________________________________________
Detailed Description
The MAX4380–MAX4384 are single-supply, rail-to-rail,
voltage-feedback amplifiers that employ current-feed-
back techniques to achieve 485V/µs slew rates and
210MHz bandwidths. Excellent harmonic distortion and
differential gain/phase performance make these ampli-
fiers an ideal choice for a wide variety of video and RF
signal-processing applications.
Applications Information
The output voltage swings to within 50mV of each sup-
ply rail. Local feedback around the output stage
ensures low open-loop output impedance to reduce
gain sensitivity to load variations. The input stage per-
mits common-mode voltages beyond the negative sup-
ply and to within 2.25V of the positive supply rail.
Choosing Resistor Values
Unity-Gain Configuration
The MAX4380–MAX4384 are internally 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.
Video Line Driver
The MAX4380–MAX4384 are low-power, voltage-feed-
back amplifiers featuring bandwidths up to 210MHz,
0.1dB gain flatness to 55MHz. They are designed to
minimize differential-gain error and differential-phase
error to 0.02% and 0.08 degrees respectively. They

have a 16ns settling time to 0.1%, 485V/µs slew rates,
and output-current-drive capability of up to 75mA
making them ideal for driving video loads.
Inverting and Noninverting Configurations
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 PC board capacitance. This can
generate undesirable poles and zeros and decrease
bandwidth or cause oscillations. For example, a nonin-
verting gain-of-two configuration (RF= RG) using 1kΩ
resistors, combined with 1pF of amplifier input capaci-
tance and 1pF of PC board capacitance, causes a
pole at 159MHz. Since this pole is within the amplifier
bandwidth, it jeopardizes stability. Reducing the 1kΩ
resistors to 100Ωextends 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
These amplifiers operate from a single +4.5V to +11V
power supply or from dual ±2.25V to ±5.5V supplies. For
single-supply operation, bypass VCC to ground with a
0.1µF capacitor as close to the pin as possible. If operat-
ing with dual supplies, bypass each supply with a 0.1µF
capacitor.
Maxim recommends using microstrip and stripline
techniques to obtain full bandwidth. To ensure that the
PC board does not degrade the amplifier’s perfor-
mance, 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:
•Don’t use wire-wrap boards; they are too inductive.
•Don’t 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 PC board with at least two layers; it should be
as free from voids as possible.
•Keep signal lines as short and as straight as possi-
ble. Do not make 90°turns; round all corners.
Rail-to-Rail Outputs,
Ground-Sensing Inputs
For +5V single-supply operation, the input common-
mode range extends from (VEE - 200mV) to (VCC
- 2.25V) with excellent common-mode rejection.
Beyond this range, the amplifier output is a nonlinear
function of the input, but does not undergo phase
reversal or latchup.
For ±5V dual-supply operation, the common-mode
range is from VEE to (VCC - 2.25V)
For +5V single-supply operation the output swings to
within 50mV of either power-supply rail with a 2kΩ
load. The input ground sensing and the rail-to-rail out-
put substantially increase the dynamic range. With a
symmetric input in a single +5V application, the input
can swing 2.95Vp-p and the output can swing 4.9Vp-p
with minimal distortion.
Low-Power Disable Mode
The disable feature (DISABLE_) allows the amplifier to
be placed in a low-power, high-output-impedance
state. When the disable pin (DISABLE_) is active, the
amplifier’s output impedance is 35kΩ. This high resis-
tance and the low 2pF output capacitance make the
MAX4380–MAX4382 and the MAX4384 ideal in
RF/video multiplexer or switch applications. For larger
arrays, pay careful attention to capacitive loading.
Refer to the Output Capacitive Loading and Stability
section.

Output Capacitive Loading and Stability
The MAX4380–MAX4384 are optimized for AC perfor-
mance. They are not designed to drive highly reactive
loads, which decrease phase margin and may produce
excessive ringing and oscillation. Figure 2 shows a cir-
cuit 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 exces-
sive peaking of the amplifier’s frequency response if
the capacitor is not isolated from the amplifier by a
resistor. A small isolation resistor (usually 10Ωto 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
15Ωisolation resistor on closed-loop response.
