General Description
The MAX4414–MAX4419 operational amplifiers com-
bine high-speed performance, low distortion, and ultra-
low supply current. Consuming just 1.6mA of supply
current per amplifier, these devices operate from a sin-
gle +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.

_______________Detailed Description
The MAX4414–MAX4419 single-supply, rail-to-rail, volt-
age-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 ampli-
fiers 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 ampli-
fier 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-sup-
ply rail with a 1kΩload. Input ground sensing and rail-
to-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 perfor-
mance. 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 ampli-
fier by a resistor. A small isolation resistor (usually 20Ω
to 30Ω) placed before the reactive load prevents ring-
ing and oscillation. At higher capacitive loads, AC per-
formance 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 22Ωisola-
tion resistor on closed-loop response.

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 com-
pensated for unity gain. When configured for unity gain,
the devices require a 24Ωfeedback resistor (RF). This
resistor improves AC response by reducing the Q of the
parallel LC circuit formed by the parasitic feedback
capacitance and inductance.
Inverting and Noninverting Configurations
Select the gain-setting feedback (RF) and input (RG)
resistor values that best fit the application. Large resis-
tor 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 nonin-
verting gain-of-two configuration (RF= RG) using 1kΩ
resistors, combined with 1.8pF of amplifier input capac-
itance 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 100Ωextends 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 RSto be equal to the
parallel combination of RFand RG(Figures 3a and 3b):

Video Line Driver
The MAX4414–MAX4419 are designed to minimize dif-
ferential gain error and differential phase error to 0.03%/
0.15°respectively, making them ideal for driving video
loads. See Figure 4.
Active Filters
The low distortion and high bandwidth of the
MAX4414–MAX4419 make them ideal for use in active
filter circuits. Figure 5 is a 15MHz lowpass, multiple-
feedback active filter using the MAX4414.
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.
Layout and Power-Supply Bypassing
These amplifiers operate from a single +2.7V to +5.5V
power supply. Bypass VCC to ground with a 0.1µF
capacitor as close to the pin as possible.
Maxim recommends using microstrip and stripline tech-
niques 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 out-
puts. Whether or not a constant-impedance board is
used, observe the following guidelines:
•Do not use wire-wrap boards due to their high induc-
tance.
•Do not use IC sockets because of the increased par-
asitic capacitance 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 possible.
Do not make 90°turns; round all corners.
