Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX4285/MAX4286 single and MAX4287/MAX4288/ MAX4387/MAX4388 dual ADC buffer amplifiers feature high-speed performance and single +3V supply operation. The MAX4285/MAX4286/MAX4288 and MAX4388 offer a disable feature that reduces power-supply current and places the outputs in a high-impedance state. All six devices operate from a +2.85V to +6.5V single supply or from ±1.425V to ±3.25V dual supplies. The commonmode input voltage range extends to the negative powersupply rail (ground in single-supply applications).

The MAX4388 requires 20mA of quiescent supply current per amplifier while achieving a 250MHz -3dB bandwidth and a 350V/µs slew rate. The combination of an 8ns (to 0.1%) settling time, 88dBc (f = 5MHz) of SFDR, and up to 100mA output drive makes these amplifiers ideal for highspeed ADC drivers for communications and instrumentation applications. In addition, when disabled, their high output impedance makes them ideal for multiplexing applications. The MAX4285/MAX4286 are available in space-saving 6-pin SOT23 and 8-pin SO packages.

The MAX4287/ MAX4387 come in 8-pin µMAX and 8-pin SO packages, while the MAX4288/MAX4388 come in 10-pin µMAX and 14-pin SO packages.
