MAX4142ESD

Manufacturer Part Number
MAX4142ESD
Description
250MHz, low-power, high-output-current, differential line driver.
Manufacturer
Maxim Integrated Products
Datasheet
The MAX4142 differential line driver combines high-
speed performance with fully symmetrical differential
inputs and outputs. With an internally set +2V/V closed-
loop gain, the MAX4142 is ideal for driving back-
terminated cables and transmission lines.
This device utilizes laser-trimmed thin-film resistors and
common-mode cancellation circuitry to deliver an out-
standing 67dB at 10MHz common-mode rejection
(CMR). Using current-feedback techniques, the
MAX4142 achieves a 250MHz -3dB (A
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.
