_______________General Desc ription
The MAX4177/MAX4277 are wide-bandwidth, fast-settling
buffer amplifiers featuring high slew rate, high precision,
high output current, and low differential gain and phase
errors. The MAX4177 is preset for unity voltage gain
(0dB), and has a small-signal -3dB bandwidth of 380MHz.
The MAX4277 is preset for a voltage gain of +2 (6dB),
and has a small-signal -3dB bandwidth of 350MHz.
The MAX4177/MAX4277 feature the high slew rate and
low power of current-mode feedback amplifiers.
However, unlike conventional current-mode feedback
amplifiers, these devices have a unique input stage that
combines the benefits of current-feedback topology
with those of the traditional voltage-feedback topology.
This combination of architectures results in low input
offset voltage and bias current, and high gain precision
and power-supply rejection.
The MAX4177/MAX4277 are ideally suited for driving
50
or 75
loads. They are the perfect choice for high-
speed cable-driving applications such as video routing.
In addition, the devices incorporate a shutdown mode
that can be used to disable the output in multiplexer
applications and to conserve power. The MAX4177/
MAX4277 are available in 8-pin DIP, SO and μMAX
packages.
