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
unity-gain stability and have a small-signal -3dB band-
width of 150MHz. The MAX4435/MAX4437 are compen-
sated 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 ana-
log-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.
