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/s slew rate. The
MAX4304, compensated for gains of +2V/V or greater,
delivers a 730MHz bandwidth and a 1000V/s 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/s 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.
