Overview

5000V/µs Slew Rate (MAX4444)
+2V/V Internally Fixed Gain (MAX4444)
External Gain Selection (MAX4445, A_VCL ≥ +2V/V)
550MHz -3dB Bandwidth
-60dB SFDR at 5MHz
Low Differential Gain/Phase: 0.07%/0.05°
Low Noise: 25nV/ at f_IN = 100kHz
Low-Power Disable Mode Reduces Quiescent Current to 3.5mA

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.

Product Details

The MAX4444 evaluation kit (EV kit) simplifies evaluation of the MAX4444 ultra-fast differential line receiver. The EV kit includes the MAX4444, which has a fixed gain of +2V/V. This EV kit can also be used to evaluate the adjustable-gain MAX4445, which is stable with a minimum gain of +2V/V. To evaluate the MAX4445, order a free sample of the MAX4445ESE along with the MAX4444 EV kit.
