________________General Description

The MAX4144/MAX4145/MAX4146 differential line

receivers offer unparalleled high-speed, low-distortion

performance. Using a three op-amp instrumentation

amplifier architecture, these ICs have fully symmetrical

differential inputs and a single-ended output. They

operate from ±5V power supplies and are capable of

driving a 150Ω load to ±3.7V. The MAX4144 has an

internally set closed-loop gain of +2V/V. The MAX4145

is optimized for gains from +1V/V to +10V/V, while the

MAX4146 is optimized for gains from +10V/V to

+100V/V. The MAX4145/MAX4146 require a single

external resistor to set the closed-loop gain.

These amplifiers use laser-trimmed, matched thin-film

resistors to deliver a common-mode rejection (CMR) of

up to 90dB at 10MHz. Using current-feedback tech-

niques, the MAX4144 achieves a 130MHz bandwidth

and a 1000V/µs slew rate. The MAX4145 achieves a

bandwidth of 180MHz and a slew rate of 600V/µs while

operating with a closed-loop gain of +1V/V, and the

MAX4146 features a bandwidth of 70MHz and a slew

rate of 800V/µs with a gain of +10V/V. Excellent differ-

ential gain/phase and noise specifications make these

amplifiers ideal for a wide variety of video and RF

signal-processing applications.

For a complete differential transmission link, use the

MAX4144/MAX4145/MAX4146 with the MAX4147 differ-

ential line driver (see the MAX4147 data sheet for more

information).
