General Description
The MAX4430/MAX4431 single and MAX4432/MAX4433
dual operational amplifiers feature wide bandwidth, 16-
bit settling times in 37ns, and low-noise/low-distortion
operation. The MAX4430/MAX4432 are compensated for
unity gain stability and have a small signal -3dB band-
width of 180MHz. The MAX4431/MAX4433 are compen-
sated for closed-loop gains of +2 or greater and have a
small-signal -3dB bandwidth of 215MHz.
The MAX4430–MAX4433 op amps require only 11mA of
supply current per amplifier while achieving 125dB open-
loop gain. Voltage noise density is a low 2.8nV/√Hz,
and provides 100dB spurious-free dynamic range
(SFDR) at 1MHz. These characteristics make these op
amps ideal for driving modern high-speed 14- and 16-
bit analog-to-digital converters (ADCs).
These high-speed op amps feature wide output voltage
swings capable of driving ADCs with ≥4V input dynamic
range and a high current output drive up to 60mA. Using
a voltage feedback architecture, the MAX4430–
MAX4433 meet the requirements of many applications
that previously depended on current feedback ampli-
fiers.
The MAX4430/MAX4431 are available in a space-sav-
ing 5-pin SOT23 package, and the MAX4432/MAX4433
are available in an 8-pin µMAX package.

Detailed Description
The MAX4430–MAX4433 are wide-bandwidth, ultra-low-
distortion, voltage-feedback amplifiers. The MAX4430/
MAX4432 are internally compensated for unity gain.
The MAX4431/MAX4433 are internally compensated for
gains of +2V/V or greater.
These amplifiers have ultra-fast 37ns (MAX4430/
MAX4432) 16-bit settling times, 100dB SFDR at 1MHz,
and 4Vp-p output swing with minimum 110dB open-
loop gain.
High-Speed ADC Input Driver Application
The MAX4430–MAX4433 op amps are ideal for driving
high-speed 14- to 16-bit ADCs. In most cases, these
ADCs operate with a charge balance scheme, with
capacitive loads internally switched on and off from the
input. The driver used must withstand these changing
capacitive loads while holding the signal amplitude sta-
bility consistent with the ADC’s resolution and, at the
same time, have a frequency response compatible with
the sampling speed of the ADC (Figure 1).
Inverting and Noninverting Configurations
The circuits typically used for the inverting and non-
inverting configurations of the MAX4430–MAX4433 are
shown in Figures 2a and 2b. The minimum uncondition-
ally stable gain values are 1 for the MAX4430/MAX4432
and 2 for the MAX4431/MAX4433. Use care in selecting
the value for the resistor marked RSin both circuits.
From dynamic stability considerations (based on the
part’s frequency response and the input capacitance of
the MAX4430–MAX4433), the maximum recommended
value for RSis 500Ω. In general, lower RSvalues will
yield a higher bandwidth and better dynamic stability,
at the cost of higher power consumption, higher power
dissipation in the IC, and reduced output drive avail-
ability. For a minimum RS value, take into consideration
that the current indicated as IFis supplied by the output
stage and must be discounted from the maximum out-
put current to calculate the maximum current available
to the load. IFcan be found using the following equa-
tion:
IF= VIN(MAX) / RS
If DC thermal stability is an important design concern,
the Thevenin resistance seen by both inputs at DC
must be balanced. This includes the resistance of the
signal source and termination resistors if the amplifier
signal input is fed from a transmission line. The capaci-
tance associated with the feedback resistors must also
be considered as a possible limitation to the available
bandwidth or to the dynamic stability. Only resistors
with small parallel capacitance specifications should
be considered.
Applications Information
Layout and Power-Supply Bypassing
The MAX4430–MAX4433 have wide bandwidth and
consequently require careful board layout. To realize
the full AC performance of these high-speed amplifiers,
pay careful attention to power-supply bypassing and
board layout. The PC board should have a large low-
impedance ground plane that is as free of voids as
possible. Do not use commercial breadboards. Keep
signal lines as short and straight as possible. Observe
high-frequency bypassing techniques to maintain the

amplifier’s accuracy and stability. In general, use sur-
face-mount components since they have shorter bodies
and lower parasitic reactance. This will result in
improved performance over through-hole components.
The bypass capacitors should include 1nF and/or
0.1µF surface-mount ceramic capacitors between each
supply pin and the ground plane, located as close to
the package as possible. Place a 10µF tantalum
capacitor at the power supply’s point of entry to the PC
board to ensure the integrity of the incoming supplies.
Input termination resistors and output back-termination
resistors, if used, should be surface-mount types and
should be placed as close to the IC pins as possible.
Driving Capacitive Loads
MAX4430–MAX4433 can drive capacitive loads.
However, excessive capacitive loads may cause ring-
ing or instability at the output as phase margin is
reduced. Adding a small isolation resistor in series with
the output capacitive load helps reduce the ringing but
slightly increases gain error (see Typical Operating
Characteristics and Figure 3).
