The MAX4444/MAX4445 differential line receivers offer unparalleled high-speed, low-distortion performance. Using a three op amp instrumentation amplifier architecture, 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 maintaining up to a 5000V/µs slew rate. Excellent differential gain/phase and noise specifications make these amplifiers ideal for a wide variety of video and RF signal-processing applications. An evaluation kit is available to speed design.
