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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
