The MAX4147 differential line driver offers high-speed

performance while consuming only 100mW of power.

Its amplifier has fully symmetrical inputs and outputs

and uses laser-trimmed, matched, thin-film resistors to

deliver 70dB CMR at 10MHz. Using current-feedback

techniques, the MAX4147 achieves a 300MHz band-

width and a 2000V/µs slew rate.

Optimized for differential, high-output-current applica-

tions such as transformer drivers, the MAX4147 drives

±2.6V into a 26.5Ω load (single-ended) or ±5.6V into a

53Ω load (differential). This device is preset for a

closed-loop gain of 2V/V. Its ultra-low 0.008%/0.03° dif-

ferential gain/phase allow for a variety of video and RF

signal-processing applications.

For power-sensitive applications, the MAX4147 has a

shutdown function that reduces supply current to less

than 1mA. In addition, superior SFDR (-82dBc at

10kHz, R

for HDSL applications.

For a complete differential transmission link, use the

MAX4147 with the MAX4144 line receiver (see the

MAX4144 data sheet for more information).
