MAX4444/MAX4445 19-1543 Rev 0 10/99 Ultra-High-Speed, Low-Distortion, Differential- to-Single-Ended Line Receivers with Enable General Description Features The MAX4444/MAX4445 differential line receivers offer 5000V/s Slew Rate (MAX4444) unparalleled high-speed, low-distortion performance. +2V/V Internally Fixed Gain (MAX4444) Using a three op amp instrumentation amplifier archi- tecture, these ICs have symmetrical differential inputs External Gain Selection and a single-ended output. They operate from 5V (MAX4445, A +2V/V) VCL supplies and are capable of driving a 100 load to 550MHz -3dB Bandwidth 3.7V. The MAX4444 has an internally set closed-loop gain of +2V/V, while the MAX4445 is compensated for -60dB SFDR at 5MHz gains of +2V/V or greater, set by an external resistor. A Low Differential Gain/Phase: 0.07%/0.05 low-power enable mode reduces current consumption to 3.5mA. Low Noise: 25nV/ Hz at f = 100kHz IN Using current-feedback techniques, the MAX4444/ Low-Power Disable Mode Reduces Quiescent MAX4445 achieve a 550MHz bandwidth while maintain- Current to 3.5mA ing up to a 5000V/s 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. Applications Ordering Information Differential-to-Single-Ended Conversion PART TEMP.
