Dual-Supply, 180MHz, 16-Bit Accurate,
Ultra-Low Distortion Op Amps
General Description
____________________________Features
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.
ꢀ 16-Bit Accurate Settling in 37ns
(MAX4430/MAX4432)
ꢀ 100dB SFDR at 1MHz, 4Vp-p Output
ꢀ 2.8nV/√Hz Input Voltage Noise Density
ꢀ 110dB (min) Open-Loop Gain
ꢀ 145V/µs Slew Rate (MAX4431/MAX4433)
ꢀ 60mA High Output Drive
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).
ꢀ Wide Voltage Swing Capable of Driving ADC
Inputs with ≥4Vp-p Input Dynamic Range
ꢀ Available in Space-Saving Packages
5-pin SOT23 (MAX4430/MAX4431)
8-pin µMAX (MAX4432/MAX4433)
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.

Note 1: The MAX4430–MAX4433 are not protected for output short-circuit conditions.
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.

The MAX4430–MAX4433 are wide-bandwidth, ultra-low-
distortion, voltage-feedback aꢀplifiers. The MAX4430/
MAX4432 are internally coꢀpensated for unity gain.
The MAX4431/MAX4433 are internally coꢀpensated for
gains of +2V/V or greater.

High-Speed ADC Input Driver Application
The MAX4430–MAX4433 op aꢀps are ideal for driving
high-speed 14- to 16-bit ADCs. In ꢀost cases, these
ADCs operate with a charge balance scheꢀe, with
capacitive loads internally switched on and off froꢀ the
input. The driver used ꢀust withstand these changing
capacitive loads while holding the signal aꢀplitude sta-
bility consistent with the ADC’s resolution and, at the
saꢀe tiꢀe, have a frequency response coꢀpatible with

If DC therꢀal stability is an iꢀportant design concern,
the Thevenin resistance seen by both inputs at DC
ꢀust be balanced. This includes the resistance of the
signal source and terꢀination resistors if the aꢀplifier
signal input is fed froꢀ a transꢀission line. The capaci-
tance associated with the feedback resistors ꢀust also
be considered as a possible liꢀitation to the available
bandwidth or to the dynaꢀic stability. Only resistors
with sꢀall parallel capacitance specifications should
be considered.
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 ꢀiniꢀuꢀ uncondition-
ally stable gain values are 1 for the MAX4430/MAX4432
Applications Information
Layout and Power-Supply Bypassing
The MAX4430–MAX4433 have wide bandwidth and
consequently require careful board layout. To realize
the full AC perforꢀance of these high-speed aꢀplifiers,
pay careful attention to power-supply bypassing and
board layout. The PC board should have a large low-
iꢀpedance ground plane that is as free of voids as
possible. Do not use coꢀꢀercial breadboards. Keep
signal lines as short and straight as possible. Observe
high-frequency bypassing techniques to ꢀaintain the

aꢀplifier’s accuracy and stability. In general, use sur-
face-ꢀount coꢀponents since they have shorter bodies
and lower parasitic reactance. This will result in
iꢀproved perforꢀance over through-hole coꢀponents.
The bypass capacitors should include 1nF and/or
0.1µF surface-ꢀount ceraꢀic capacitors between each
supply pin and the ground plane, located as close to
the package as possible. Place a 10µF tantaluꢀ
capacitor at the power supply’s point of entry to the PC
board to ensure the integrity of the incoꢀing supplies.
Input terꢀination resistors and output back-terꢀination
resistors, if used, should be surface-ꢀount 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 ꢀay cause ring-
ing or instability at the output as phase ꢀargin is
reduced. Adding a sꢀall 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).
