General Description
The MAX4178/MAX4278 are ±5V, wide-bandwidth, fast-
settling, closed-loop buffers featuring high slew rate, high
precision, high output current, low noise, and low differen-
tial gain and phase errors. The MAX4178, with a -3dB
bandwidth of 330MHz, is preset for unity voltage gain
(0dB). The MAX4278 is preset for a voltage gain of +2
(6dB) and has a 310MHz -3dB bandwidth.
The MAX4178/MAX4278 feature the high slew rate and
low power that are characteristic of current-mode feed-
back amplifiers. However, unlike conventional current-
mode feedback amplifiers, these devices have a
unique input stage that combines the benefits of cur-
rent-feedback topology with those of the traditional volt-
age-feedback topology. This combination results in low
input offset voltage and bias current, low noise, and
high gain precision and power-supply rejection.
The MAX4178/MAX4278 are ideally suited for driving
50
or 75 loads. They are the perfect choice for high-
speed cable-driving applications, such as video routing.
The MAX4178/MAX4278 are available in DIP, SO,
space-saving MAX, and SOT23 packages.
