330MHz / Gain of !/Gain of @ Closed-Loop Buffers
_______________General DescriptionThe 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/MAX4278feature 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/MAX4278are ideally suited for driving
50Ωor 75Ωloads. They are the perfect choice for high-
speed cable-driving applications, such as video routing.
The MAX4178/MAX4278 are available in DIP, SO, and
space-saving µMAX and SOT23 packages.

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.
