MAX4447/MAX4448/MAX4449 General Description The MAX4447/MAX4448/MAX4449 single-ended-todifferential 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 compensated 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. MAX4447/MAX4448/MAX4449 6500V/µs, Wideband, High-Output-Current, SingleEnded-to-Differential Line Drivers with Enable ABSOLUTE MAXIMUM RATINGS VCC to VEE ..........................................................................+12V Voltage on IN, EN, OUT+, OUT-, RG ....(VEE - 0.3V) to (VCC + 0.3V) Output Short-Circuit Duration to GND ...........................Indefinite Continuous Power Dissipation (TA = +70°C) 16-Pin Narrow SO (derate 20mW/°C above +70°C) ..1600mW Operating Temperature Range ...........................-40°C to +85°C Storage Temperature Range ............................-65°C to +150°C Lead Temperature (soldering, 10s) .................................+300°C Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
