MAX4434–MAX4437
Single-Supply, 150MHz, 16-Bit Accurate,
Ultra-Low Distortion Op Amps
General Description
The MAX4434/MAX4435 single and MAX4436/MAX4437
dual operational amplifiers feature wide bandwidth, 16-bit
settling time in 23ns, and low-noise/low-distortion operation. The MAX4434/MAX4436 are compensated for unitygain 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 smallsignal, -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.

Note 1: The MAX4434–MAX4437 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.

MAX4434–MAX4437
Single-Supply, 150MHz, 16-Bit Accurate,
Ultra-Low Distortion Op Amps
Detailed Description
The MAX4434–MAX4437 are wide-bandwidth, ultra-low
-distortion, 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 open-loop gain.
High-Speed ADC Input
Driver Application
The MAX4434–MAX4437 op amps are ideal for drivinghigh-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 Figure 2a and Figure 2b. The minimum uncondition-
ally 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 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 bypassRF

ing 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).
