19-2200; Rev 0; 10/01
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.
