The MAX4447/MAX4448/MAX4449 single-ended-to-
differential line drivers are designed for high-speed
communications. 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. For greater design flexibility, the
MAX4448/MAX4449 allow for variable gain selection
using external gain-setting resistors. A low-power
enable mode reduces current consumption below 5.5mA
and places the outputs in a high-impedance state.
The MAX4447/MAX4448/MAX4449 can deliver differen-
tial output swings of ±6.2V from ±5V supplies with a
50Ω load. Excellent differential gain/phase and noise
specifications make these amplifiers ideal for a wide
variety of video and RF signal-processing and transmis-
sion applications.
