... Using current feedback for greater bandwidth, these devices deliver full-power bandwidths up to 405MHz and feature slew rates as high as 6500V/µs. The MAX4447 has a fixed gain of +2V/V and a small-signal bandwidth of 430MHz. The MAX4448/ MAX4449 have small-signal bandwidths of 330MHz and 400MHz, respectively, and are internally compen- sated for minimum gain configurations of +2V/V and +5V/V, respectively ...

... Applications Information Grounding and Bypassing Use high-frequency design techniques when designing the PC board for the MAX4447/MAX4448/MAX4449: • Use a multilayer board with one layer dedicated as the ground plane. • Do not wire-wrap or use breadboards, due to high inductance. • Avoid IC sockets, due to high parasitic capacitance and inductance. • ...
