MAX4277

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 highspeed 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 MAX packages.
