Ultra-Small, Low-Cost, 210MHz, Single-Supply
Op Amps with Rail-to-Rail Outputs
General Description
Features
ꢀ Ultra-Small SC70-5, SOT23-5, and SOT23-8
The MAX4450 single and MAX4451 dual op amps are
unity-gain-stable devices that combine high-speed per-
Packages

ꢀ High Speed
®
formance with Rail-to-Rail outputs. Both devices oper-
ate from a +4.5V to +11V single supply or from ±±.±5V
to ±5.5V dual supplies. The common-mode input volt-
age range extends beyond the negative power-supply
rail (ground in single-supply applications).
210MHz -3dB Bandwidth
55MHz 0.1dB Gain Flatness
485V/µs Slew Rate
The MAX4450/MAX4451 require only 6.5mA of quies-
cent supply current per op amp while achieving a
±10MHz -3dB bandwidth and a 485V/µs slew rate. Both
devices are an excellent solution in low-power/low-
voltage 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 a space-
saving 8-pin SOT±3.

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 at 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.

tance and 1pF of PC board capacitance, causes a pole
at 159MHz. Since this pole is within the amplifier band-

but could limit output swing by adding ±00Ω in parallel
with the amplifier’s load resistor. Table 1 lists suggest-

Detailed Description
The MAX4450/MAX4451 are single-supply, rail-to-rail,
voltage-feedback amplifiers that employ current-feed-
back techniques to achieve 485V/µs slew rates and
±10MHz bandwidths. 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.

The output voltage swings to within 55mV of each sup-
ply rail. Local feedback around the output stage
ensures low open-loop output impedance to reduce
gain sensitivity to load variations. The input stage per-
mits common-mode voltages beyond the negative sup-
ply and to within ±.±5V of the positive supply rail.

and the rail-to-rail output substantially increase the
dynamic range. With a symmetric input in a single +5V
application, the input can swing ±.95Vp-p and the out-
put can swing 4.9Vp-p with minimal distortion.
Maxim recommends using microstrip and stripline tech-
niques 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 care-
ful attention to inputs and outputs to avoid large para-
sitic capacitance. Whether or not you use a constant-
impedance board, observe the following design guide-
lines:
Output Capacitive Loading and Stability
The MAX4450/MAX4451 are optimized for AC perfor-
mance. They are not designed to drive highly reactive
loads, which decrease phase margin and may produce
excessive ringing and oscillation. Figure ± shows a cir-
cuit that eliminates this problem. Figure 3 is a graph of
the optimal isolation resistor (R ) vs. capacitive load.

• Don’t use wire-wrap boards; they are too inductive.
Figure 4 shows how a capacitive load causes exces-
sive peaking of the amplifier’s frequency response if
the capacitor is not isolated from the amplifier by a
resistor. A small isolation resistor (usually ±0Ω 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
±7Ω isolation resistor on closed-loop response.
• Don’t use IC sockets; they increase parasitic capaci-
tance 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 possi-
ble. Do not make 90° turns; round all corners.
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.
Rail-to-Rail Outputs,

The input common-mode range extends from
(V - ±00mV) to (V

mode rejection. Beyond this range, the amplifier output
is a nonlinear function of the input, but does not under-
go phase reversal or latchup.
The output swings to within 55mV of either power-
supply rail with a ±kΩ load. The input ground sensing
