________________Detailed Description
The MAX4144/MAX4145/MAX4146 are low-distortion,
differential line receivers that feature high bandwidths
and excellent common-mode rejection, making them
ideal for balanced, high-speed data transmission sys-
tems.
The MAX4144 has a preset gain of +2V/V and achieves
a 130MHz -3dB bandwidth, a 1000V/µs slew rate, and
common-mode rejection (CMR) of 70dB at 10MHz. The
MAX4145 and MAX4146 use a single external resistor to
set the closed-loop gain from +1V/V to +10V/V for the
MAX4145, or greater than +10V/V for the MAX4146. The
MAX4145 achieves a -3dB bandwidth of 180MHz, a
slew rate of 600V/µs, and CMR of 75dB at 10MHz when
operating in the unity-gain configuration. The MAX4146
attains a -3dB bandwidth of 70MHz, a slew rate of
800V/µs, and CMR of 90dB at 10MHz when operating
with a closed-loop gain of +10V/V.
Differential inputs make the MAX4144/MAX4145/
MAX4146 ideal for applications with high common-
mode noise, such as receiving T1 or xDSL transmis-
sions over a twisted-pair cable. Excellent differential
gain and phase, along with low noise, also suit them to
video applications and RF signal processing.
For a complete differential transmission link, use the
MAX4144/MAX4145/MAX4146 amplifiers with the
MAX4147 line driver, as shown in the Typical Applica-
tion Circuit.
___________Applications Information
Grounding, Bypassing,
and PC Board Layout
Adhere to the following high-frequency design tech-
niques when designing the PC board for the
MAX4144/MAX4145/MAX4146.
• The printed circuit board should have at least two
layers: the signal layer and the ground plane.
• Do not use wire-wrap boards—they are too
inductive.
