MAXIM MAX4178/MAX4278 Manual

Update: 30 September, 2023

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 differential 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 feedback 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 50Ω or 75Ω loads. 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.
