6500V/µs, Wideband, High-Output-Current, Single-  
Ended-to-Differential Line Drivers with Enable  
78/MAX49  
General Description  
Features  
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.

♦ -78dB SFDR at 100kHz  
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.

♦ Ultra-Low Noise: 23nV/√Hz at f = 1MHz
