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. MAX4444/MAX4445 Ultra-High-Speed, Low-Distortion, Differentialto-Single-Ended Line Receivers with Enable ABSOLUTE MAXIMUM RATINGS VCC to VEE ...........................................................................+12V Voltage on IN+, IN-, EN, OUT+, OUT-, RG, REF..............................(VEE - 0.3V) to (VCC + 0.3V) Current Into IN+, IN-, RG, EN .............................................20mA Output Short-Circuit Duration ...........................Indefinite to GND Continuous Power Dissipation (TA = +70°C) 16-Pin Narrow SO (derate 20mW/°C above +70°C) ...1600mW Operating Temperature Range ...........................-40°C to +85°C Storage Temperature Range .............................-65°C to +150°C Lead Temperature (soldering, 10sec) .............................+300°C Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
