General Description

The MAX4430/MAX4431 single and MAX4432/MAX4433

dual operational amplifiers feature wide bandwidth, 16-

bit 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 band-

width of 180MHz. The MAX4431/MAX4433 are compen-

sated 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 open-

loop 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 16-

bit 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 ampli-

fiers.

The MAX4430/MAX4431 are available in a space-sav-

ing 5-pin SOT23 package, and the MAX4432/MAX4433

are available in an 8-pin µMAX package.
