General Description

The MAX4104/MAX4105/MAX4304/MAX4305 op amps

feature ultra-high speed, low noise, and low distortion in

a SOT23 package. The unity-gain-stable MAX4104

requires only 20mA of supply current while delivering

625MHz bandwidth and 400V/µs slew rate. The

MAX4304, compensated for gains of +2V/V or greater,

delivers a 730MHz bandwidth and a 1000V/µs slew

rate. The MAX4105 is compensated for a minimum gain

of +5V/V and delivers a 410MHz bandwidth and a

1400V/sec slew rate. The MAX4305 has +10V/V mini-

mum gain compensation and delivers a 340MHz band-

width and a 1400V/µs slew rate.

Low voltage noise density of 2.1nV/√Hz and -88dBc

spurious-free dynamic range make these devices ideal

for low-noise/low-distortion video and telecommunica-

tions applications. These op amps also feature a wide

output voltage swing of ±3.7V and ±70mA output current-

drive capability. For space-critical applications, they

are available in a miniature 5-pin SOT23 package.
