MAX4145ESD+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
________________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).
