19-2200; Rev 1; 12/08
Single-Supply, 150MHz, 16-Bit Accurate,
Ultra-Low Distortion Op Amps
The MAX4434/MAX4435 single and MAX4436/MAX4437
dual operational amplifiers feature wide bandwidth, 16bit settling time in 23ns, and low-noise/low-distortion
operation. The MAX4434/MAX4436 are compensated for
unity-gain stability and have a small-signal -3dB bandwidth of 150MHz. The MAX4435/MAX4437 are compensated for closed-loop gains of +5 or greater and have a
small-signal, -3dB bandwidth of 150MHz.
The MAX4434–MAX4437 op amps require only 15mA of
supply current per amplifier while achieving 115dB
open-loop gain. Voltage noise density is a low 2.2nV/√Hz
and provides 97dB 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 and a high-current output drive up to 65mA. Using
a voltage feedback architecture, the MAX4434–
MAX4437 meet the requirements of many applications
that previously depended on current feedback amplifiers.
The MAX4434/MAX4435 are available in space-saving
5-pin SOT23 packages and the MAX4436/MAX4437 are
available in 8-pin µMAX® packages.

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.

Single-Supply, 150MHz, 16-Bit Accurate,
Ultra-Low Distortion Op Amps
The MAX4434–MAX4437 are wide-bandwidth, ultra-lowdistortion, voltage-feedback amplifiers. The MAX4434/
MAX4436 are internally compensated for unity gain.
The MAX4435/MAX4437 are internally compensated for
gains of +5V/V or greater.
These amplifiers have ultra-fast 35ns (MAX4434/
MAX4436) 16-bit settling times, -97dB SFDR at 1MHz,
and 4Vp-p output swing with minimum 115dB openloop gain.
High-Speed ADC Input Driver Application
The MAX4434–MAX4437 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 stability 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 noninverting configurations of the MAX4434–MAX4437 are
shown in Figures 2a and 2b. The minimum unconditionally stable gain values are 1 for the MAX4434/MAX4436
and 5 for the MAX4435/MAX4437. Use care in selecting
the value for the resistor marked RS in both circuits. From
dynamic stability considerations (based on the part’s frequency response and the input capacitance of the
MAX4434–MAX4437), the maximum recommended
value for RS is 500Ω. In general, lower RS values 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 availability.
For a minimum RS value, take into consideration that the
current indicated as IF is supplied by the output stage
and must be discounted from the maximum output current to calculate the maximum current available to the
load. IF can be found using the following equation:
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 capacitance 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.

Figure 1. Typical Application Circuit
The MAX4434–MAX4437 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 lowimpedance 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 VCC
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
The MAX4434–MAX4437 can drive capacitive loads.
However, excessive capacitive loads may cause ringing 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).
