Low-Power, +3V/+5V, 400MHz Single-Supply
Op Amps with Rail-to-Rail Outputs
General Description
Features
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.

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, volt-
age-feedback aꢀplifiers achieve high slew rates and
bandwidths, while consuꢀing only 1.6ꢀA of supply
current per aꢀplifier. Excellent harꢀonic distortion and
differential gain/phase perforꢀance ꢀake these aꢀpli-
fiers an ideal choice for a wide variety of video and RF
signal-processing applications.
Output Capacitive Loading and Stability
The MAX4414–MAX4419 are optiꢀized for AC perfor-
ꢀance. They are not designed to drive highly reactive
loads. Such loads decrease phase ꢀargin and ꢀay
produce excessive ringing and oscillation. The use of
an isolation resistor eliꢀinates this probleꢀ (Figure 1).
Figure 2 is a graph of the Optiꢀal Isolation Resistor
Internal feedback around the output stage ensures low
open-loop output iꢀpedance, reducing gain sensitivity
to load variations. This feedback also produces
deꢀand-driven current bias to the output transistors.
(R ) vs. Capacitive Load.
ISO
The Sꢀall-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 aꢀplifier’s frequency
response if the capacitor is not isolated froꢀ the aꢀpli-
fier by a resistor. A sꢀall isolation resistor (usually 20Ω
to 30Ω) placed before the reactive load prevents ring-
ing and oscillation. At higher capacitive loads, AC per-
forꢀance is controlled by the interaction of the load
capacitance and the isolation resistor. The Sꢀall-Signal
Gain vs. Frequency with Capacitive Load and 22Ω
Isolation Resistor graph shows the effect of a 22Ω isola-
tion resistor on closed-loop response.
Rail-to-Rail Outputs, Ground-Sensing Input
The MAX4414–MAX4419 input coꢀꢀon-ꢀode range
extends froꢀ (V - 0.1V) to (V
- 1.5V) with excellent
CC
EE
coꢀꢀon-ꢀode rejection. Beyond this range, the aꢀpli-
fier output is a nonlinear function of the input, but does
not undergo phase reversal or latchup.
The output swings to within 105ꢀV of either power-sup-
ply rail with a 1kΩ load. Input ground sensing and rail-
to-rail output substantially increase the dynaꢀic range.
With a syꢀꢀetric input in a single +5V application, the

Coaxial cable and other transꢀission lines are easily
driven when properly terꢀinated at both ends with their
characteristic iꢀpedance. Driving back-terꢀinated
transꢀission lines essentially eliꢀinates the line’s
capacitance.

resistor values that best fit the application. Large resis-
tor values increase voltage noise and interact with the
aꢀplifier’s input and PC board capacitance. This can
generate undesirable poles and zeros and decrease
bandwidth or cause oscillations. For exaꢀple, a nonin-

Choosing Resistor Values
resistors, coꢀbined with 1.8pF of aꢀplifier input capac-
itance and 1pF of PC board capacitance, causes a
pole at 114MHz. Since this pole is within the aꢀplifier
bandwidth, it jeopardizes stability. Reducing the 1kΩ
resistors to 100Ω extends the pole frequency to
1.14GHz, but could liꢀit output swing by adding 200Ω
in parallel with the aꢀplifier’s load resistor.
Unity-Gain Configuration
The MAX4414/MAX4416/MAX4418 are internally coꢀ-
pensated for unity gain. When configured for unity gain,
the devices require a 24Ω feedback resistor (R ). This
F
resistor iꢀproves AC response by reducing the Q of the
parallel LC circuit forꢀed by the parasitic feedback
capacitance and inductance.
Note: For high gain applications where output offset
voltage is a consideration, choose R to be equal to the

The MAX4414–MAX4419 are designed to ꢀiniꢀize dif-
ferential gain error and differential phase error to 0.03%/
0.15° respectively, ꢀaking theꢀ ideal for driving video
loads. See Figure 4.

Maxiꢀ recoꢀꢀends using ꢀicrostrip and stripline tech-
niques to obtain full bandwidth. Design the PC board
for a frequency greater than 1GHz to prevent aꢀplifier
perforꢀance degradation due to board parasitics.
Avoid large parasitic capacitances at inputs and out-
puts. Whether or not a constant-iꢀpedance 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-ꢀount instead of through-hole coꢀpo-
nents for better high-frequency perforꢀance.
ADC Input Buffer
Input buffer aꢀplifiers 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 iꢀpedance often changes very
rapidly during the conversion cycle, ꢀeasureꢀent
accuracy ꢀust be ꢀaintained using an aꢀplifier with
very low output iꢀpedance at high frequencies. The
coꢀbination of high speed, fast slew rate, low noise,
and a low and stable distortion over load ꢀake the
MAX4414–MAX4419 ideally suited for use as buffer
aꢀplifiers in high-speed ADC applications.
• Use a PC board with at least two layers; it should be
as free froꢀ voids as possible.
• Keep signal lines as short and as straight as possible.
Do not ꢀake 90° turns; round all corners.
Layout and Power-Supply Bypassing
These aꢀplifiers operate froꢀ a single +2.7V to +5.5V
power supply. Bypass V
to ground with a 0.1µF
CC
capacitor as close to the pin as possible.
