The MAX4142 differential line driver combines high-
speed performance with fully symmetrical differential
inputs and outputs. With an internally set +2V/V closed-
loop g a in, the MAX4142 is id e a l for d riving b a c k-
terminated cables and transmission lines.

width, a 70MHz 0.1dB bandwidth, and a 1400V/µs slew
rate. Excellent differential gain/phase error and noise
specifications make this amplifier an excellent choice
for a wide variety of video and RF signal-processing
applications.

The MAX4142 operates from ±5V power supplies and
requires only 12.5mA of quiescent current. The output
stage is capable of driving a 100Ω load to ±6V (differ-
entially) or to ±3V (single-ended). The MAX4142 is
available in a space-saving 14-pin SO package. For a
pin-compatible, higher speed differential line driver,
see the MAX4147 data sheet.
