The MAX4444/MAX4445 differential line receivers offer
unparalleled high-speed, low-distortion performance.
Using a three op amp instrumentation amplifier archi-
tecture, these ICs have symmetrical differential inputs
and a single-ended output. They operate from ±5V
supplies and are capable of driving a 100Ω load to
±3.7V. The MAX4444 has an internally set closed-loop
gain of +2V/V, while the MAX4445 is compensated for
gains of +2V/V or greater, set by an external resistor. A
low-power enable mode reduces current consumption
to 3.5mA.
Using current-feedback techniques, the MAX4444/
MAX4445 achieve a 550MHz bandwidth while maintain-
ing up to a 5000V/µs slew rate. Excellent differential
gain/phase and noise specifications make these ampli-
fiers ideal for a wide variety of video and RF signal-pro-
cessing applications. An evaluation kit is available to
speed design.
