Ultra-Small, Low-Cost, 85MHz Op Amps with
Rail-to-Rail Outputs and Disable
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 quinescent
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.

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.

Detailed Description
The MAX4389/MAX4390/MAX4392–MAX4396 are dualsupply, 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 Configuration
The MAX4389/MAX4390/MAX4392–MAX4396 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 MAX4389/MAX4390/MAX4392–MAX4396 are lowpower, voltage-feedback amplifiers featuring large-signal (2V P-P) bandwidths of 90MHz and 0.1dB largesignal gain flatness of 24MHz. They are designed to
minimize 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 Configurations
Select the gain-setting feedback (RF) and input (RG)
resistor values to fit your application. Large resistor values increase voltage noise and interact with the amplifier’s input and PC board capacitance. This can
generate undesirable poles and zeros and decrease
bandwidth or cause oscillations. For example, a noninverting gain-of-two configuration (RF = RG) using 2kΩ
resistors, combined with 1pF of amplifier input capacitance and 1pF of PC board capacitance, causes a pole
at 79.6MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. 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
supplies. Bypass each supply with a 0.1µF capacitor as
close to the pin as possible.
Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. To ensure that the PC
board 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 capacitance and inductance.
•
Use surface-mount instead of through-hole components 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 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).

The MAX4389/MAX4390/MAX4392–MAX4396 are optimized 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 amplifier 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.
