MAXIM MAX4430, MAX4433 Technical data

General Description

The MAX4430/MAX4431 single and MAX4432/MAX4433
dual operational amplifiers feature wide bandwidth, 16­bit 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 band­width of 180MHz. The MAX4431/MAX4433 are compen­sated for closed-loop gains of +2 or greater and have a
small-signal -3dB bandwidth of 215MHz.

The MAX4430–MAX4433 op amps require only 11mA of
supply current per amplifier while achieving 125dB open­loop 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 16­bit analog-to-digital converters (ADCs).

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 ampli­fiers.

The MAX4430/MAX4431 are available in a space-sav­ing 5-pin SOT23 package, and the MAX4432/MAX4433
are available in an 8-pin µMAX package.
