MAX4278
MAX4278 is Gain of +1/Gain of +2 Closed-Loop Buffers manufactured by Maxim Integrated.
- Part of the MAX4178 comparator family.
- Part of the MAX4178 comparator family.
Description
The MAX4178/MAX4278 are ±5V, wide-bandwidth, fastsettling, 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 -3d B bandwidth of 330MHz, is preset for unity voltage gain (0d B). The MAX4278 is preset for a voltage gain of +2 (6d B) and has a 310MHz -3d B 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 bines the benefits of current-feedback topology with those of the traditional voltage-feedback topology. This bination results in low input offset voltage and bias current, low noise, and high gain precision and power-supply...
