General Description
The MAX4450 single and MAX4451 dual op amps are
unity-gain-stable devices that combine high-speed performance with rail-to-rail outputs. Both devices operate
from a +4.5V to +11V single supply or from ±2.25V to
±5.5V dual supplies. The common-mode input voltage
range extends beyond the negative power-supply rail
(ground in single-supply applications).
The MAX4450/MAX4451 require only 6.5mA of quiescent supply current per op amp while achieving a
210MHz -3dB bandwidth and a 485V/µs slew rate. Both
devices are an excellent solution in low-power/lowvoltage systems that require wide bandwidth, such as
video, communications, and instrumentation.
The MAX4450 is available in the ultra-small 5-pin SC70
package, while the MAX4451 is available in spacesaving 8-pin SOT23 and SO packages.

Detailed Description
The MAX4450/MAX4451 are single-supply, rail-to-rail,
voltage-feedback amplifiers that employ current-feedback techniques to achieve 485V/µs slew rates and
210MHz 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.
The output voltage swings to within 55mV 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 beyond the negative supply and to within 2.25V of the positive supply rail.
Applications Information
Choosing Resistor Values
Unity-Gain Configuration
The MAX4450/MAX4451 are internally compensated for
unity gain. When configured for unity gain, the devices
require a 24Ω resistor (RF) in series with the feedback
path. 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 (R
F
) 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 1kΩ
resistors, combined with 1pF of amplifier input capacitance 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 100Ω extends the pole frequency to 1.59GHz,
but could limit output swing by adding 200Ω in parallel
with the amplifier’s load resistor. Table 1 lists suggested feedback and gain resistors, and bandwidths for
several gain values in the configurations shown in
Figures 1a and 1b.

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 constantimpedance board, observe the following design guidelines:
• Don’t use wire-wrap boards; they are too inductive.
• Don’t 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.
Rail-to-Rail Outputs,
Ground-Sensing Input
The input common-mode range extends from
(VEE- 200mV) to (VCC- 2.25V) with excellent commonmode 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 55mV of either powersupply rail with a 2kΩ load. The input ground sensing
and the rail-to-rail output substantially increase the
dynamic range. With a symmetric input in a single +5V
application, the input can swing 2.95V
P-P
and the out-
put can swing 4.9V
P-P
with minimal distortion.
Output Capacitive Loading and Stability
The MAX4450/MAX4451 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 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. Figure 5 shows the effect of a
27Ω isolation 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.
