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 feedback amplifiers.
However, unlike conventional currentmode 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 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 50Ω or 75Ω loads.
They are the perfect choice for highspeed cable-driving applications, such as video routing.
The MAX4178/MAX4278 are available in DIP, SO, and space-saving µMAX and SOT23 packages.
