MAX4414–MAX4419
General Description
The MAX4414–MAX4419 operational amplifiers combine high-speed performance, low distortion, and ultralow supply current. Consuming just 1.6mA of supply
current per amplifier, these devices operate from a single +2.7V to +5.5V supply, have Rail-to-Rail® outputs,
and exhibit a common-mode input voltage range that
extends from 100mV below ground to within 1.5V of the
positive supply rail.
The MAX4414/MAX4416/MAX4418 single/dual/quad op
amps are unity-gain stable and achieve a 400MHz -3dB
bandwidth with a 200V/µs slew rate. The MAX4415/
MAX4417/MAX4419 single/dual/quad op amps are
compensated for closed-loop gains of +5V/V or greater
and achieve a 150MHz -3dB bandwidth with a 470V/µs
slew rate. The combination of high-speed, ultra-low
power, and low-distortion makes the MAX4414–
MAX4419 ideal for low-power/low-voltage, high-speed
portable systems such as video, communications, and
instrumentation.
The MAX4414/MAX4415 single and MAX4416/
MAX4417 dual amplifiers are available in space-saving
8-pin µMAX and SO packages, while the MAX4418/
MAX4419 quad amplifiers are available in a 14-pin
TSSOP 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 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 MAX4414–MAX4419 single-supply, rail-to-rail, voltage-feedback amplifiers achieve high slew rates and
bandwidths, while consuming only 1.6mA of supply
current per amplifier. 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.
Internal feedback around the output stage ensures low
open-loop output impedance, reducing gain sensitivity
to load variations. This feedback also produces
demand-driven current bias to the output transistors.
Rail-to-Rail Outputs, Ground-Sensing Input
The MAX4414–MAX4419 input common-mode range
extends from (VEE - 0.1V) to (VCC - 1.5V) 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.
The output swings to within 105mV of either power-supply rail with a 1kΩ load. Input ground sensing and railto-rail output substantially increase the dynamic range.
With a symmetric input in a single +5V application, the
input can swing 3.6Vp-p, and the output can swing
4.6Vp-p with minimal distortion.
Output Capacitive Loading and Stability
The MAX4414–MAX4419 are optimized for AC performance. They are not designed to drive highly reactive
loads. Such loads decrease phase margin and may
produce excessive ringing and oscillation. The use of
an isolation resistor eliminates this problem (Figure 1).
Figure 2 is a graph of the Optimal Isolation Resistor
(RISO) vs. Capacitive Load.
The Small-Signal Gain vs. Frequency with Capacitive
Load and No Isolation Resistor graph in the Typical
Operating Characteristics 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 20Ω
to 30Ω) 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. The Small-Signal
Gain vs. Frequency with Capacitive Load and 22Ω
Isolation Resistor graph shows the effect of a 22Ω isolation resistor on closed-loop response.

MAX4414–MAX4419
Pin Description
Coaxial cable and other transmission lines are easily
driven when properly terminated at both ends with their
characteristic impedance. Driving back-terminated
transmission lines essentially eliminates the line’s
capacitance.
___________Applications Information
Choosing Resistor Values
Unity-Gain Configuration
The MAX4414/MAX4416/MAX4418 are internally compensated for unity gain. When configured for unity gain,
the devices require a 24Ω feedback resistor (RF). This
resistor improves AC response by reducing the Q of the
parallel LC circuit formed by the parasitic feedback
capacitance and inductance.
RG
Inverting and Noninverting Configurations
Select the gain-setting feedback (RF) and input (RG)
resistor values that best fit the 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 1kΩ
resistors, combined with 1.8pF of amplifier input capacitance and 1pF of PC board capacitance, causes a
pole at 114MHz. Since this pole is within the amplifier
bandwidth, it jeopardizes stability. Reducing the 1kΩ
resistors to 100Ω extends the pole frequency to
1.14GHz, but could limit output swing by adding 200Ω
in parallel with the amplifier’s load resistor.
Note: For high gain applications where output offset
voltage is a consideration, choose RS to be equal to the
parallel combination of RF and RG (Figures 3a and 3b):

Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. Design the PC board
for a frequency greater than 1GHz to prevent amplifier
performance degradation due to board parasitics.
Avoid large parasitic capacitances at inputs and outputs. Whether or not a constant-impedance board is
used, observe the following guidelines:
• Do not use wire-wrap boards due to their high inductance.
• Do not use IC sockets because of the increased parasitic capacitance and inductance.
ADC Input Buffer
Input buffer amplifiers can be a source of significant
errors in high-speed ADC applications. The input buffer
is usually required to rapidly charge and discharge the
ADC’s input, which is often capacitive (see Output
Capacitive Loading and Stability). In addition, since a
high-speed ADC’s input impedance often changes very
rapidly during the conversion cycle, measurement
accuracy must be maintained using an amplifier with
very low output impedance at high frequencies. The
combination of high speed, fast slew rate, low noise,
and a low and stable distortion over load make the
MAX4414–MAX4419 ideally suited for use as buffer
amplifiers in high-speed ADC applications.
• 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.
Layout and Power-Supply Bypassing
These amplifiers operate from a single +2.7V to +5.5V
power supply. Bypass V CC to ground with a 0.1µF
capacitor as close to the pin as possible.
