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 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.

The MAX4447/MAX4448/MAX4449 can deliver differential 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 transmission applications.

Applications

  • Differential Line Driver
  • Differential Pulse Amplifier
  • High-Speed Differential Transmitter
  • Single-Ended-to-Differential Conversion
  • Video and RF Signal Processing and Transmission
  • xDSL Applications

Product Detail

The MAX4447 evaluation kit (EV kit) simplifies evaluation of the MAX4447 high-speed differential line driver. The EV kit includes the MAX4447, which has a fixed gain of +2V/V, but it can also be used to evaluate the adjustable-gain MAX4448 (stable with a minimum gain of +2V/V) or the MAX4449 (stable with a minimum gain of +5V/V). To evaluate the MAX4448 or MAX4449, order a free sample of the MAX4448ESE or MAX4449ESE along with the MAX4447 EV kit.
