MAX4387/MAX4388 dual ADC buffer amplifiers feature high-speed performance and single +3V supply opera-tion. The MAX4285/MAX4286/MAX4288 and MAX4388offer 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 common-mode input voltage range extends to the negative power-

supply rail (ground in single-supply applications). These devices require 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 high-speed ADC drivers for communications and instrumenta-tion 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.
